SUPERSiC® Dummy Wafers
It is still common for silicon dummy wafers to be made from reclaimed Silicon (Si) material. Si reclaimed wafers require recovery, cleaning, pro-tection, and tracking. Costs for reclaimed Si wafers can exceed $100,000 per year, depending on the size of the fab. The lifetime of a Si reclaimed dummy wafer is determined by its cleaning frequency.
Comparison of Silicon Carbide and Zircaloy4 Cladding
There are 264 fuel rods per fuel assely, and 193 fuel asselies modulus of elasticity and Poisson’s ratio are for Direct Sintered Silicon Carbide at 20 , which are taken from CoorsTek . The ultimate tensile strength is also the value at 20 wall model is used to calculate the stress profile.
All three substances will decrease the electrical conductivity of a silicon carbide product. In general, however, silicon carbide has a purity of over 99.9995%. The three most commonly produced commercial grades of silicon carbide are sintered silicon carbide (SSC), nitride bonded silicon carbide (NBSC) and reactive bonded silicon carbide (RBSC).

Calcium carbide - Wikipedia
Production. Calcium carbide is produced industrially in an electric arc furnace from a mixture of lime and coke at approximately 2,200 °C (3,990 °F). This is an endothermic reaction requiring 110 kilocalories (460 kJ) per mole and high temperatures to drive off the carbon monoxide. This method has not changed since its invention in 1892: CaO + 3 C → CaC 2 + CO

7 Cost Issues | Ceramic Fibers and Coatings: Advanced
The SiC fibers shown in Figure 7-2 (the upper line shows the projected price level at 1,000 kilograms [2,200 lbs] per year; the lower line shows 100,000 kilograms [220,000 lbs] per year) do indeed appear to be “expensive,” well above the price line for carbon fibers. It may not be appropriate, however, to compare the cost of SiC fibers
