Silicon Carbide - Digitalfire
Silicon Carbide is a non oxide ceramic and is used in a wide range of products that must perform in thermally (high heat and heat shock) and mechanically demanding appliions. It is employed in both abrasives and wear resistant parts for its hardness; in refractories and ceramics for its resistance to heat and low thermal expansion; and in electronics for its thermal conductivity and other

Moreover, such simulations can provide an estimate for the shortest annealing time and lowest annealing temperature, which result in a desired active concentration. For instance, for Setup 2, it is evident that an annealing step of 5 min at 1650°C is sufficient to achieve an identical activation as compared to annealing for 30 min at 1700°C.
