Boron carbide and boron-rich boron carbide were prepared at Rutgers University. This was done by sintering powder mixes of Rutgers-made boron carbide powder, synthesized using the rapid carbo-thermal reduction (RCR) process along with high purity
Hexoloy SiC Sensor Tubes | Saint-Gobain Performance …
Hexoloy® alpha silicon carbide (Hexoloy) is a single-phase silicon carbide product that is extremely pure and uniform. Silicon carbide has been mass produced since 1893 because of its hardness, but purity and porosity have always been limiting factors.

Pure silicon carbide is colourless and transparent. The green to black colour of the industrial product results from impurities, mostly iron. The green specimen is a somewhat purer, slightly harder, but more friable form (Wright, 2006). Although silicon carbide has
Pure CVD silicon carbide wafer carriers | Engineer Live
Morgan Technical Ceramics has launched pure chemical vapour deposition silicon carbide (CVD SiC) wafer carriers for high temperature metal organic chemical vapour deposition (MOCVD) processing. Pure CVD SiC wafer carriers enable manufacturers of high brightness light emitting diodes (LEDs) using gallium nitride (GaN) deposition to significantly increase their yield and to meet the growing
PureSiC CVD Silicon Carbide | CoorsTek
Chemical vapor deposition (CVD) silicon carbide resists corrosion in extreme environments while maintaining the high strength and excellent wear properties of silicon carbide. This capability, coined with the exceptional purity of 99.9995%, is helping make the ultra-clean manufacturing used in semiconductor production run faster and more efficiently.
The silicon produced via this process is called metallurgical grade silicon and is at least 98% pure. Using this method, silicon carbide, SiC, can form. However, provided the amount of SiO 2 is kept high, silicon carbide may be eliminated, as explained by this 2
