12.The ductile to brittle transition temperature in ceramic is around ____ of melting point (Tm)? Correct Answer 0.5 Tm

The ceramic are generally brittle in nature at room temperature, hence the ductile to brittle transition temperature must be above the room temperature. For most of the ceramics, it comes around 0.5Tm
