3.1 The oxidation of silicon carbide refractories at elevated temperatures is an important consideration in the appliion of these refractories. The product of oxidation is amorphous silica or cristobalite, depending upon the temperature at which oxidation takes place. This oxide formation is associated with expansion and degradation of strength.
This holds true for other industrial appliions where high-power and high-temperature demands preclude the use of more common silicon material. CrystX silicon carbide is available from GTAT in bulk-crystal form and ready for wafering. Presently, the available form factor for CrystX silicon carbide is 150 mm diameter and with a target usable
