It is known that the less is the porosity of a tool material the better are the cutting property and performance of a tool manufactured with the help of powder metallurgy margules 1980. It is equivalent to the existence of a defect which can cause stress concentration accelerate crack growth reduce the bonding strength between grains and seriously affect the mechanical properties of ceramics under the action of friction force the pores may connect with each other to form a crack source accelerating the. Their hardness apart from other factors ceramic materials porosity has a sizable effect on it. The international journal of applied ceramic technology publishes cutting edge applied research and development work focused on commercialization of engineered ceramics products and processes.

Properties affecting thermal stress resistance of ceramics are reviewed and testing methods are considered. The sources and calculation of thermal stresses are considered together with the factors involved in thermal stress resistance factors. Maksarov et al 2014. Factors affecting strength of ceramics strength of ceramics is thus determined by many factors.

Lower the stress a material can support.
