Carbothermic reduction of cobalt and nickel tungstates
Inorganic Materials, 2006Data are presented on the formation sequence of metallic, carbide, and intermediate oxide phases in the carbon reduction of CoWO4 and NiWO4. The surface reaction between CoWO4 particles and solid carbon yields the mixed carbide Co6W6C, while the reaction with the CO originating from carbon vaporization yields the intermetallic phase Co7W6.

Carbothermal reduction and nitridation of aluminium hydroxide
Journal of Materials Science, 1996Carbothermal reduction and nitridation of aluminium hydroxide was investigated by weight-loss measurement and X-ray diffraction. Experimental results indicated that aluminium hydroxide was first dehydrated to aluminium oxide and then reduced and nitrided to aluminium nitride. Aluminium oxynitride and Al2O were found to be intermediate products.

Carbothermic reduction of mechanically activated celestite
International Journal of Mineral Processing, 2009Abstract Effects of dry milling on the carbothermic reduction of celestite were examined. Celestite and coke mixture was milled up to 120 h in a planetary ball mill. Unmilled and milled mixtures and their black ashes from carbothermic reduction were characterized by a combination of X-ray diffraction (XRD) analysis, scanning electron microscope ...
