Relationship between microstructure and mechanical properties in fully vttrified stoneware

摘要

Fully vitrified stoneware tiles are very important low-porosity products obtained by high-sintering of unglazed ceramic bodies and used for exterior application and as frost-resistant materials. The dense microstructure of the fired tiles is characterized y strongly interlocked crystals of quartz and mullite embedded in a amorphous glassy phase. Vickers microhardness (4.94-6.09 Gpa), Yong's modulus (68.7-73.6 Gpa) and abrasion resistance (1.48-1.84 g/30x30 tile) of industrial fully vitrified stoneware tiles were measured and well represent the mechanical properties of the tiles. microstructure of the fired
