What is the coefficient of thermal expansion of silicon carbide?

What is the coefficient of thermal expansion of silicon carbide? Correct Answer 4.3 * 10-6

Silicon carbide has a good coefficient of thermal expansion of 4.3 * 10-6/oC and that of alumina is 9 * 10-6/oC. The coefficients of thermal expansion of silicon nitride and sialon are 3.2 * 10-6/oC and 3.04 * 10-6/oC respectively. Among these common ceramics, partially stabilized zirconia (PSZ) has the highest value of 10.6 * 10-6/oC.
