It is deemed that to obtain toughened mullite fibre directly in the sintering course by using high temperature phase change of andalusite is feasible.

认为，利用红柱石的高温相交，在陶瓷烧结过程中直接制取莫来石纤维是可行的。

In this paper, mineral composition and mullitization and related products of andalusite from Xijiang was studied. This can offer theory instruction for fabricating low creep mullite-corundum materials.

本论文以新疆红柱石精矿为研究对象，研究了它的矿物组成，高温下的莫来石化及其相关制品的性能，为生产莫来石-刚玉质低蠕变材料提供了理论指导。

The results showed that the mullite content increased with temperature and sokingtime increased,and mullitization of andalusite with samller size or more impurities was faster.

实验证明：随煅烧温度的升高和保温时间的延长，莫来石的转化量增加；粒度越小或杂质含量越高的红柱石莫来石化速度越快。

As the temperature increases, content of quartz, anhydrite, and hematite in coal ash decrease in reducing conditions and some new mineral phases are formed during heating process. The content of mullite formed in the heating process is the mayor reason of high melting temperature of the ash. Anorthite at high temperature lowers the ash fusion temperature.

随着温度的升高，煤灰中石英、硬石膏、赤铁矿等结晶矿物含量逐渐减少，生成新的矿物质，莫来石的生成是导致淮南煤灰熔点高的主要原因，钙长石起到降低灰熔点的作用。

The result show that the samples are compactest when a-Al2O3/ content is 10wt% at 1450℃, zircon start to decomposes at 1350℃, little mullite are found at 1450℃, there are lots of mullite at 1500℃, apparent poroes become more, bulk density falls.

结果表明，1350℃时硅酸锆已经开始分解，添加a-Al2O3/为10%、温度为1450℃时烧结体最致密，相对密度达到95%，1450℃时已有少量莫来石相形成，1500℃时形成较多莫来石相，气孔增多，体积密度降低。

Bauxite based mullite was prepared with grade Ⅱ broken bauxite (3 mm) and broken coal gangue(3 mm) as starting material according to formula w(Al2O3)=68%~72% in bauxite based mullite grogs.

以Ⅱ等高铝矾土碎矿(≤3 mm)和煤矸石碎矿(≤3 mm)为原料，按照矾土基莫来石熟料w(Al2O3)=68%~72%的要求，将它们按一定比例混合配制成混合料，接着将混合料湿磨至0.044 mm以均化化学成分，经湿法挤泥成型、烘干后分别在1 550℃、1 600℃和1 700℃煅烧6 h，冷却后测定其显气孔率和体积密度以确定烧结温度。

The result shows that a great mass of kaolinite and boehmite in Zhungar coal are turned ioto mullite. There is no boehmite and less kaolinite found in Shenhua coal, so there won't be too much mullite formed.

结果表明，准格尔煤粉中包含的大量高岭石和勃姆石为莫来石的大量生成提供了条件，神华煤中不含勃姆石，高岭石的含量也不多，莫来石的生成量很少。

The composite membranes with different ratio of Al〓O〓 to SiO〓 are composed of amorphous matter or amorphous matter and γ-Al〓O〓 when sintered at 600℃. The composite membrane with mullite composition go thrsought the following phase transition as the temperature rising from 200℃ to 1100℃: amorphous matter and boehmite (200℃)→amorphous matter and γ-Al〓O〓(4001000℃)→mullite and α-Al〓O〓.

经热处理后不同化学组成的复合陶瓷膜由无定形态或者无定形态和γ-Al〓O〓组成，具有莫来石化学成分的复合膜随着烧结温度的升高，其组成分别为无定形态和勃姆石（200℃）、无定形态和γ-Al〓O〓（400-1000℃），并在1100℃时析出莫来石和α-Al〓O〓。
