The effect of time and temperature on the density and strength of α‐Sic was studied and mathematically modeled using a central composite experimental design. A sintering temperature of 2150°C for 1.7 h maximized the flexural strength and densification values. However, temperatures above 2200°C promoted abnormal grain growth, with resulting appreciable decreases in strength. Flexural strength increased exponentially with increasing density for specimens with densities <92% of theoretical.
