Micro silicon carbide tension specimen were prepared with straight, curved, and notched gage lengths. These were tested to failure and the strengths analyzed by Weibull statistics. Fractographic analysis confirmed that strength limiting flaws were etch grooves …
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.
Typical Silicon Carbide (SiC) Properties SiC is an artificial (man-made) mineral known for its very high hardness and abrasion resistance. Common appliions include pump seals, valve components, and wear-intensive appliions such as rollers and paper
High purity: CoorsTek PureSiC® CVD Silicon Carbide uses chemical vapor deposition (CVD) to produce ultra- pure (>99.9995%) ceramic parts and coatings. CoorsTek UltraClean™ Siliconized Silicon Carbide (Si:SiC) is a unique silicon carbide in which metallic silicon (Si) infiltrates spaces between the grains ─ allowing extremely tight tolerances even for large parts.

Silicon carbide is mostly used in appliions that require high thermal conductivity. Its extreme hardness, resulting extraordinary resistance to wear, and excellent chemical resistance are the distinguishing qualities of this material. It has become an irreplaceable cornerstone of chemical process engineering, milling processes and dispersion technology.
Silicon carbide (SiC), also known as carborundum is an exceedingly hard, synthetically produced crystalline compound of silicon and carbon. It occurs in nature as the extremely rare mineral Moissanite. Until 1929, silicon carbide was the hardest synthetic material known. It has a hardness rating of 9, close to that of diamond. In addition to hardness, […]
