Silicon Carbide SiC Material Properties - Accuratus
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.

Minimum size is 3.0 mm but will soon be replaced by 5.0 mm. Density: 3.20-3.30 gm/cc This alumina media is most often referred to as MULLITE with approximately 35% SiO2. It has the advantage of being higher in density than glass and lower density than other aluminas.
Ceramic Spheres—A Novel Solution to Deep Sea Buoyancy …
These spheres, sintered at 1600 C and with 1.0 mm of wall thickness, have achieved buoyancy of more than 54%. As the sphere’s wall thickness was reduced (e.g., 0.5 mm), their buoyancy reached 72%. The mechanical performance of such spheres has
The presented article describes a simple technique to fabrie open/closed cell silicon carbide (SiC) foams. The SiC foams, especially pyrolyzed either at 1200 °C (PSiC_12) or 1500 °C (PSiC_15), offered the best thermophysical properties suitable for advance thermal management systems. Both PSiC_12 and PSiC_15 possessed almost equal concentrations of open and closed …

Silicon Nitride Ceramics - International Syalons
Silicon Nitride Ceramics Silicon nitrides (Si3N4) are a range of advanced engineering ceramics characterised by high strength, toughness and hardness and excellent chemical and thermal stability. Silicon nitride was discovered in the mid-nineteenth century but did not lend itself to ease of fabriion, due to its covalently bonded nature. This initially led to the development […]
