Abstract
Densification process, phase component and mechanical strength of the feldspathic porcelain bodies were investigated. Packing ratio and flexural strength showed a linear correlation and its gradient (k-value) indicated a degree of the effect for the reinforcement during densification. The k-value was greatly influenced by mullite/glass ratio, and needlelike crystals of mullite was considered to accelerate the reinforcement of bodies. Fracture toughness increased with the residual amount of quartz. It is considered that, although the mechanisms are different, mullite and quartz strengthen the body.
