Introduction In recent years, Y-TZP( tetragonal zirconia stabilized by yttrium) ceramic materials have attracted extensive attention in oral medicine as novel dental restoration materials.
Meanwhile the interspaces inside the materials are filled up with glassy phases.
Conclusions Glass phases are introduced in ceramic materials by adding in small amount of frit powders.

The Thinking on Multiphase Materials Jingkun Guo*, Huamin Kou, Yubai Pan State Key Lab of High Performances Ceramics and Superfine Microstructure Shanghai Institute of Ceramics, Chinese Academy of Sciences 1295 Ding-Xi Road, Shanghai, 200050, China *jkguo@sunm.shcnc.ac.cn Keywords: Multiphase materials, ceramics, alumina, core-shell Abstract.The main problems for multiphase materials are the even mixing and the bonding or reacting among two or more phases, as well as the states of their grain boundaries.
Even mixing Even mixing between each other material is important for multiphase materials.
Reactions for multiphase materials It's required that no reactions occurs among each phases for multiphase materials.
Therefore, multiphase materials are a good target for the material designing.

The results show materials with high thermal conductivity such as tungstenbased materials are more resistant to thermal fatigue cracking than conventionally used hot work tool steels for HPDC dies.
The results show die materials with high thermal conductivities containing tungsten are more resistant to thermal fatigue cracking than commonly used ferrous die materials in HPDC conditions.
