Silicon Carbide (SiC) is one of the most frequently employed industrial refractory ceramics, as it boasts highly dense and strong mechanical properties that make it highly suitable for applications involving high temperatures and pressures.
Neutron diffraction and ballistic experiments have provided insight into how thermally induced pre-stress affects the confinement of circular SiC tiles to thermal pre-stress conditions, leading to their confinement into thermal pre-stress conditions and subsequent pre-stress levels. Micro-CT post mortem analyses demonstrated how confinement modified Hertzian cone trajectory, thus decreasing damage.
High Temperature Resistance
Silicon Carbide possesses impressive mechanical strength and toughness at high temperatures, while also being resistant to acids corrosion. Due to these properties, it makes an excellent material choice for use in kiln components, nozzles and sealing rings, as well as for use in metallurgical industries, semiconductor wafer preparation fixtures and nuclear fuel cladding materials.
Ceramic silicon carbide offers excellent corrosion, abrasion and erosion resistance as well as shock resistance, high temperature creep resistance and thermal shock absorption properties – ideal properties for use as seal material in pump applications operating across a broad spectrum of environments.
LS-DYNA was used to model the impact response of SiC tile array strike faces using a two-step simulation framework. The initial step simulated confinement and pre-stress through misfit contact simulation, producing hoop stresses that were then mapped into the model for subsequent ballistic simulation; stress results were very consistent with measured data.
High Strength
Silicon Carbide is an extremely hard material with great strength. As such, its resilience makes it ideal for wear applications like mechanical seals and bulletproof plates, where repeated contact between hard particles or surfaces exposes it to repeated stress.
SiC is known for its exceptional chemical stability and can resist acids and alkalis, making it an excellent material to use in harsh industrial environments. Furthermore, its ability to withstand extreme temperatures and abrasion make SiC one of the top wear-resistant ceramic materials available today.
Utilizing the LS-DYNA multiphysics simulation software, hoop stresses in both SiC tile and steel collar were measured. A misfit contact simulation was initialised followed by mapping results into ballistic simulation for stressed and unstressed specimens; accuracy for both was found to be approximately 5×10-5 mstrains which is comparable with tensile test results. Due to being manufactured into many shapes and sizes RB SiC can be utilized across many applications.
High Resistance to Corrosion
Silicon carbide is one of the hardest and most durable ceramic materials on the market, possessing outstanding mechanical strength at high temperatures with low creep and thermal shock resistance properties. Furthermore, silicon carbide exhibits excellent corrosion resistance – resisting both acids and lyes without degradation to its integrity.
Due to its stable Si-C bond structure, silicon carbide ceramic material forms a protective surface layer of silicon oxide which provides protection from chemicals and other corrosives that could otherwise attack it, making it an invaluable choice for use in chemical plants, mills and other equipment.
Saint-Gobain Hexoloy SA ceramic is a pressureless sintered silicon carbide material. When compared with reaction bonded SiC, pressureless sintered SiC offers lower densities, higher purity levels and superior mechanical properties such as tensile strength and bulk wave speed. Furthermore, pressureless sintered SiC is highly resistant to hydrofluoric acid corrosion – making it the go-to ceramic choice for power and metallurgy applications as well as bulletproof plates designed to withstand high velocity projectiles.
High Resistance to Abrasion
Silicon Carbide Ceramic Lining Tiles and Plates offer unparalleled protection from extreme abrasion, high temperatures, chemical exposure, impact, downtime reduction costs and replacement expenses. They last longer than steel or standard ceramics for increased productivity while decreasing downtime and replacement expenses.
Reaction bonded silicon carbide ceramic (RSIC/SISIC) is an engineering material composed of 7-15% silicon metal and some unreacted carbon, such as unreacted coal or petroleum coke. Duratec specializes in offering RSIC/SISIC in different shapes and sizes to meet various application needs across mining, steel production, coal mining, chemical industries, raw material-making industries as well as mechanical sealing or surface sandblasting treatments.
RSIC/SISIC has a Mohs hardness of 9.5 and is harder than sapphire but not diamond. It is resistant to abrasion and corrosion with superior oxidation resistance, thermal shock resistance and chemically inert properties that extend equipment lifespan and provide good stability – ideal as wear resistant material in chutes, cyclones or silos for prevent equipment abrasion that reduces lifespan by prolonging service life.
