Silicon carbide offers superior hardness, thermal conductivity and chemical resistance – qualities which make it suitable for numerous industrial applications, including thermocouple protection tubes, temperature measuring tubes, burner nozzles and special-shaped components. Furthermore, its low density saves both space and weight while its toughness safeguards against stress or pressure damage.
Brake Discs and Pads
Silicon carbide (SiC), more commonly referred to as carborundum, is an extremely hard ceramic that can be shaped into components for cars, helicopters and aircraft brake rotors, armored plates and bulletproof vests. SiC is a wide bandgap semiconductor found naturally in moissanite minerals but mass-produced since 1893 for use as an abrasive.
Ceramic material features low density, high strength and exceptional thermo-physical properties – including an extremely stable coefficient of friction and excellent wear resistance – making it suitable for brake discs and pads.
Material for this brake pad is created by sintering together metal powder and scouring agents into a compact form, then pyrolyzing. This creates a ceramic binding phase which improves comfort performance of the pad while isotropically aligned fibers and reduced pore size lead to efficient thermal energy conduction resulting in more stable pads than organically bonded mass-produced pads and being suitable for heavier loads.
Engine Components
Sintered silicon carbide mechanical seals offer exceptional resistance to corrosion in aggressive media environments and offer excellent tribological properties, making them suitable for numerous industrial applications. Furthermore, their heat and thermal shock resistance makes them an attractive solution that weighs half as much as steel counterparts.
These characteristics make these materials suitable for missile nozzles, ballistic armour plates, engine components and aerospace applications. Aerospace applications particularly benefit from this material’s resistance to vibrations and extreme temperatures during fast flight; saving on fuel consumption while increasing performance.
Pressureless Sintered Silicon Carbide (PSiC) is made using solid-state sintering with a low melting point to produce highly dense and strong ceramic parts. This technique has several advantages over hot-pressing sintering such as reduced production costs, easier material blending, higher strength, wider grain size distribution, less distortion under high temperature conditions, and excellent comprehensive properties. GAB Neumann uses PSiC manufactured in both Europe and North America for use in its process equipment parts as it boasts the best corrosion, wear resistance properties of all fine ceramic materials used today.
Ballistic Armour Plates
RBSC ceramic is one of the hardest on the market, retaining its hardness at high temperatures while offering superior corrosion and wear resistance compared to steel. Furthermore, its weight is nearly one half that of its counterpart.
Ideal ballistic protection requires material which fractures and erodes projectiles before they penetrate an armor surface, by absorbing impact energy and deflecting it, often through inter-granular fractures and erosion processes.
Patent No. 5,372,978 documents the inventors’ discovery of a silicon carbide composite material used as armor. This ceramic has superior ballistic stopping power compared to similar hot pressed boron carbide ceramic pieces.
Reaction bonded silicon carbide (RBSC) can be formed by infiltrating compacts of mixed SiC and carbon particles with liquid silicon, creating more SiC that bonds to initial particles in an initial reaction that bonds more SiC together to form one dense body which can then be sintered at high temperatures to form hard, strong and dense material that can be machined with expensive diamond tools to precise tolerances.
Aerospace Components
Aerospace equipment must perform reliably in harsh conditions, with components that are both durable and lightweight – our sintered silicon carbide products fulfill both criteria, making them invaluable components for aerospace manufacturing.
Sintered silicon carbide thermocouple protection tubes from us provide sensors with protection from harmful gases and particles to avoid inaccurate readings and extend sensor lifespan. They also withstand high temperatures for reduced maintenance costs in harsh environments.
At Innomedix, we offer products to enhance accuracy and speed in industrial metrology equipment such as CMMs and positioning equipment. These products feature high specific stiffness, low thermal expansion rates and excellent tribological and electrical properties – key characteristics found among other ceramics like CVD sic that must be machined after production. Furthermore, reaction-sintered and sintered silicon carbide production allows net near shape production reducing machining time and waste by starting off close to final shape and eliminating wasteful machining operations after production compared to CVD sic which must be machined after production thereby saving machining time and wasteful machining operations after production has taken place compared with CVD sic which must be machined after production has taken place reducing wasteful post machining time and waste associated with CVD sic which must be machined post production subsequently.
