ABSTRACT:
A composite ceramic block gauge and its preparing method is disclosed. The ceramic block gauge comprises a tungsten carbide (WC) reinforced phase and a chromium carbide (Cr.sub.3 C.sub.2) matrix. The finished block gauge possesses excellent properties such as hardness and corrosion resistance and high reflectivity. The block gauges made from Cr.sub.3 C.sub.2 /WC composites can be calibrated using the traditional optical interferometry techniques.
