Product Details:

Silicon carbide ceramics have the best oxidation resistance among carbides, but between 1000-1400°C, the oxidation rate of SiC in the air is higher. The volume resistivity of silicon carbide does not change much in the range of 1000-1500°C. With their good chemical stability, high mechanical strength, and thermal shock resistance. Silicon carbide wafers are frequently applied in the semiconductor, solar photovoltaic industries.
