摘要：

To develop an effective process for titanium powders production,a calciothermic reduction process of pigment titanium dioxide(w(TiO2)>98%),based on the preform reduction process(PRP),was investigated by means of XRD,SEM and EDS.In this process,the mixture of TiO2 powder and CaCl2 was pressed into pieces as feed preform and was reduced by calcium vapor.Titanium powders was recovered after leaching from the reduced preform with hydrochloric acid and deionized water.The results indicate when the mass ratio of CaCl2 to TiO2 is about 1:4 and at a constant temperature of 1 273 K for 6 h in vacuum furnace,titanium powders with 99.55% purity by EDS analysis and irregular shape(8-15 μm in particle size) are obtained.
