Mullite Whiskers and Mullite-whisker Felt [PDF]
The Naval Surface Warfare Center has developed processes for the preparation of mullite (3(Al2O3)(dot)2(SiO2)) whiskers and mullite-whisker felt. Three patents on the technology were issued in 1990.

Mechanical Properties of Mullite-SiC Whisker Composites
Mechanical properties of hot-pressed mullite-SiC whisker composites were studied in relation to the whisker content and chemical composition of matrix. Grain growth of mullite was suppressed by the existence of SiC whisker in the matrix, but the densification was not inhibited by the loading of whisker up to 30 vol%.

Mullite production by valorization of a hydrodesulphurization catalyst waste
Due to its high alumina and silica content, Ni–Mo catalyst waste is a suitable, amorphous raw material for producing aluminosilicate phases. Thermal treatment of the waste at 1200°C for 30 min yields a material containing 50 wt.% mullite and exhibiting 96% overall crystallinity. The addition of amorphous silica significantly enhances mullite formation:

Abstract The interaction behavior between iron oxide‐bearing slags and carbon‐bonded MgO refractory (MgO‐C) containing calcium magnesium aluminate (CMA) was investigated at 1400°C, 1500°C, and 1600°C. After the iron oxide was reduced by the carbon from the MgO‐C refractory, a significant amount of MgO and metallic iron was observed to precipitate and ...
