This paper introduces preparing processes of acicular mullite adopted at home and abroad, then predicts that future researches will focus on the effect of oxides\' doping on the growth of acicular crystals and the industrialized production of porous acicular mullite materials.

The friction and wear of rod-like mullite dispersed yttria stabilized tetragonal zirconia polycrystals (MDZ) sliding against a high-chromium cast iron in 5%NaOH solution containing 2wt%SiO_2 as the abrasive particles was investigated on an MM-200 test rig in a block-on-ring configuration.

Effect of Mullite on Property of Aluminium Titanate;

Research on thermal shock resistance of alumina-aluminium titanate-mullite ceramics;

The influence of sintering technique on crystalline phases and microstructures of mullite synthesized;

Effects of different types alumina powders and amount of active alumina added on andalusite decomposition,primary mullitization and secondary mullitization were studied by analyzing XRD data.

Temperature and soaking time on mullitization of andalusite were studied by analyzing the XRD data.

The current status and progress in the preparation of mullite precursor powders by chemicalmethods and the mullitization mechanism at low temperatures are reviewed.
