Silicon carbide plates are one of the most frequently used industrial and engineering materials due to their hardness and strength. This guide will outline their various uses across a range of applications.
Silicon carbide is the preferred general-purpose material for mechanical seals and pump parts due to its hardness, chemical resistance and low oxidation at high temperatures – as well as having exceptional flexural strength.
Silicon Carbide Ceramic Plates
Silicon carbide plates are an integral component of modern armor solutions such as ballistic shields and barricades, providing multi-threat protection from threats such as armor-piercing projectiles and high velocity fragments while offering exceptional chemical agent defenses. Furthermore, their lightweight construction allows soldiers greater mobility and comfort during combat operations.
These plates boast exceptional strength while remaining resistant to high temperatures and less prone to damage than other materials. Furthermore, they are non-toxic and inert for safe use in various environments.
Not like other ceramic materials, these plates do not expand when heated. Made of synthetic silica combined with carbon during sintering process to form tough yet resilient material resistant to chemical attacks and corrosion.
Sintering can be used to produce various types of ceramic, including reaction-bonded silicon carbide (RBSC). RBSC is commonly used in heating devices like kiln furniture due to its superior thermal shock resistance. Furthermore, it’s often made into wear components like grinding wheels and mechanical seals due to its strong abrasion and corrosion resistance properties; additionally it may be combined with other materials, like titanium for advanced ceramic composites.
Applications
Silicon carbide ceramic plates are integral parts of modern protective gear and armored vehicles, offering exceptional resistance against various threats. Their extreme hardness, lightweight structure and superior protection make them invaluable. Resistant to high impact and abrasion as well as corrosion and thermal expansion; additionally they’re toxicologically safe and easy to maintain – qualities which make Silicon Carbide Ceramic Plates essential components.
Silicon Carbide ceramics are among the most versatile technical ceramics on the market and find applications across industries that demand high performance – such as 3D printing, ballistics, chemical production, energy technology and energy storage technology. Furthermore, silicon carbide ceramics provide outstanding wear resistance and have excellent dimensional stability properties.
Ballistic tests require dissipating much of an initial projectile’s kinetic energy through ceramic fracture and fragmentation, consuming much of its hardness and compressive strength in the process. Therefore, selecting a ceramic with high fracture toughness and hardness is crucial.
An effective solution is a metal-ceramic composite (MMC). This form of armour comprises both ceramic and metallic components, with the metal component acting to hinder or stop crack propagation by plastically stretching its faces and plastically stretching any crack growth in ceramic material. MMCs offer up to five times greater protection than monolithic ceramics in this regard.
Characteristics
Silicon carbide ceramic plates exhibit unique characteristics depending on their manufacturing method. Reaction bonded silicon carbide (SiSiC), for instance, boasts high strength at high temperatures with minimal creep, as well as excellent resistance against damage and chemical corrosion; furthermore it can withstand thermal shocks up to 1400 deg C as well as being electrically semi-conductive with an impressively low coefficient of expansion and low coefficient expansion ratios.
SiSiC plates’ high hardness and wear resistance make them an excellent choice for cut-off wheels and grinding wheels, refractory materials, ceramic coatings and semiconductor substrates, refractories as well as industrial equipment such as mechanical seals and pumps, semiconductor processing equipment, electrical insulation plates and wear-resistant components.
Ballistic tests showed the plate to perform exceptionally against Level III and III+ bullets, thanks to its ceramic’s high hardness which caused it to fracture shear-mode rather than bend-mode, thereby consuming less of the projectile’s energy, further decreasing impact force on targets and creating smaller fragments that reduced penetration further still. Furthermore, its compressive and shear strengths provided more force resistance against penetration despite fractures occurring, with high compressive/shear strengths acting as constraints against damaged pieces which allowed for consistent results across various thicknesses/damage levels across various thicknesses/damages levels across various ceramic thicknesses/damage levels across various thicknesses/damages/levels across various thicknesses/damage levels across various thicknesses/damages/damages/damages levels. This effect was consistent across various thicknesses/damages/damages/levels/damages/damages with no variations between results from ceramic thicknesses/damages levels/damages/damage levels, further increasing projectile penetration forces against projectile penetration forces when impact forces were applied against targets by more fragmentation from fragmentation than from impact force on targets; further fragmentation further reduced overall impact force on targets as fragmentation caused further fragmentation caused further fracture fragmentation; additionally caused further fragmentation due to fragmentation processes occurring on targets as fragmentation reduced impact forces as penetration decreased overall impact force on target; similarly this result was consistent across thicknesses and damage levels across different ceramic thicknesses/damages levels/damages and damage levels used against. This result was consistent across thicknesses used against projectile penetration; consequently consistent across thicknesses used against penetration forces applied. This result was consistent across ceramic thickness and damage levels used; consistently throughout various thickness/damage levels increased with projectile penetration against target forces increased to reduced overall impact force reduced overall force reduction off target reduced overall impact forces reduced further reduced overall. This result was further reduced when penetrated penetration was further reduced further increased force resistance against projectile penetration forces against projectile penetration forces when measured against penetration forces across various thickness/damages levels used against levels used throughout thickness/damages as well as damage levels used allowing projectile penetration force resistance against projectile penetration as opposed to increased projectile penetration levels used across various ceramic thickness/damages used against projectile penetration forces as expected as well. compared across thickness/damages etc vs against projectile penetration by force levels for projectile penetration of projectile penetration force resistant projectile penetration by force was resistance increasing projectile penetration forces being resist penetration against penetration forces to resistance force increased force against penetrate penetration levels than project vs resistance forcing projectile penetration forces against project allowing project reducing penetration levels when resist penetration forces increased when increased force against project vs etc vs penetration; consistently consistently. This result consistent across various thickness vs etc vs resistance. This result across thicknesss etc vs
Materials
Silicon carbide ceramic is an advanced material widely utilized across numerous industrial sectors due to its outstanding chemical resistance, temperature stability and thermal expansion characteristics. Furthermore, due to being very hard and durable it makes an ideal material choice for bulletproof helmets and vests that protect against ballistic threats like bullets and shrapnel.
Ceramic armor plates typically consist of a composite of materials that combine SiC’s bulletproof abilities with additional elements such as boron carbide or ultra-high molecular-weight polyethylene (UHMWPE). This combination enhances flexibility, impact resistance and overall performance of the protective shield.
Sintered SiC, such as Saint-Gobain’s Hexoloy brand, is made by melting raw materials into granules before fusing them together at high temperatures and pressures using various forming methodologies, resulting in fully densified ceramics with exceptional end use temperature performance.
Reaction bonded SiC (RBSiC), commonly referred to as RBSiC, is produced through reaction sintering of porous carbon feedstock with molten silicon. This results in an extremely pure ceramic that offers excellent thermal shock resistance – perfect for components like kiln furniture. However, oxide-bonded SiC provides an economical alternative and may be suitable for items exposed to temperatures between 1300C-1350C (2500oF). Both versions of RBSiC boast incredible strength, toughness, wear resistance properties that make them great allies in their application!
