Nucleation and growth of mullite whiskers from lanthanum-doped aluminosilicate melts

, 2002
Nucleation and growth of mullite whiskers in the La2O3-Al2O3-SiO2 system were investigated in the 1500degrees-1700degreesC temperature range. A differential thermal analysis (DTA) showed that the mullitization temperature decreases from 1350degreesC to ...

Synergic process of molybdenum recovery and ceramic preparation for clean and efficient utilization of industrial leaching residues

Cleaner Engineering and Technology
Ammonia-leaching residues of roasted molybdenite concentrates are intractable wastes and are mostly stockpiled in factories. Common treatments suffer from low Mo recovery and secondary pollution. This study has developed a synergistic process involving a

Oxidation of SiC-Whisker/Mullite Composites in Dry Air

Journal of the Ceramic Society of Japan, 1989
Oxidation behavior of mullite composites containing 10 to 30vol% of SiC-whisker (SiC-w) has been studied at 1300°C in dry air. As the volume fraction of SiC-w increased, the weight gain increased. The weight gain curve obeyed the parabolic law for the SiC-w content of 10vol% and at the oxidation time shorter than 200h.

Preparation of mullite whiskers from kaolinite using CuSO4 as fluxing agent

, 2004
Mullite whiskers were produced by firing of kaolin at 1400degrees-1550degreesC. CuSO4 was used as fluxing agent. Before firing, spray drying and baking with flour and leaven were employed to give free space to the powders.
