查询词典 mullite

The traditional ceramic semifinished materials are the aluminum silicate system, the production phase are mainly the mullite, the solid phase reaction temperature are quite high, generally in 1200℃ about; But after joining the wollastonite, turns the calcium silicate system, the high temperature resultant for the anorthite and the cristobalite, reduced the solid phase reaction temperature largely, approximately for 1000℃~1050℃, and the anorthite assumes acicular.

传统的陶瓷坯料为硅酸铝系统，生成的物相主要为莫来石，固相反应温度比较高，一般在1200℃左右；而加入硅灰石后变成硅酸钙系统，高温生成物为钙长石和方石英，大幅降低了固相反应温度，大约为1000℃～1050℃，且钙长石呈针状。

Slag test indicates that andalusite has no obvious effect on penetration. Slag penetrates along boundaries of bauxite or mullite. Al2O3 from bauxite dissolves into slag to form CA6, anorthite, gehlenite and other low melting phases which precipitate during cooling.

渣蚀试验表明，红柱石时侵蚀无明显影响，熟料液相沿莫来石和矾土骨料晶界向内渗透，氧化铝逐渐浓解与液相、渣中的氧化钙形成CA5和钙长石、黄长石等低熔相，在冷却过程中，钙长石和黄长石从液相中析出。

Mullite is a kind of important engineering ceramic material with high temperature mechanical stability and good thermal shock resistance.

高温性能稳定、抗热震性好的莫来石是一种重要的工程陶瓷材料。

When the temperature reaches 1350℃, the cristobalite and mullite phases reduce a few, and more cordierite phases appear.

当热处理温度达到1350℃时，方英石及莫来石的含量略有减少，并出现较多的堇青石相。

When the temperature reaches 1200℃, cristobalite and mullite phases appear.

当温度为1200℃时，则出现方英石及莫来石相。

The phase composition was composed of silicon carbide, alumina, mullite and cristobalite.
