Ceramic specimens containing 30% kaoline and 70% burnt clay containing 25% water
were ,prepared by standard casting .Their properties (density ,apparent porosity, and apparent
water absorption) were determined. Ultrasonic test method as nondestructive method were
used to determine acoustic impedance (Z) by Puls velocity measurements. A close relation is
explicitly that is found and which is related its sintering behaviour.
