solid state sintering

In this method, the decomposition of BaCO-3, which is the major reaction rate limiting step in the conventional solid state reaction process, is excluded and so the sintering temperature and holding time required for the completion of the reaction decrease.

本方法不包括传统反应法中限制反应速率的BaCO3分解反应，因而与传统固态反应法相比，其合成温度及保温时间大大降低，从而可以合成超细粉末。

固态相变-热压烧结制备Ti3Al/TiC+Al2O3陶瓷复合材料

The results show that this process greatly decreases the slumping and distortion of tungsten heavy alloy, increases the homogeneity of the microstructure and local hardness, etc, because of the formation of three dimensional rigid net backbone with tetrakaidecahedron in the solid state sintering stage.

由于在固相烧结阶段形成了坚固的十四面体形的三维连通网络骨架，阻碍了液相烧结中钨颗粒偏析所引起的变形，合金的性能和显微组织的均匀性大大提高。

The results indicate that sintering temperature has an apparent effect on the formation of the spinel structure, and the solid state reaction is complete at 800 ℃.

结果表明：煅烧温度对尖晶石结构的形成有较明显的影响，当温度达到800℃时固相反应完全。
