Direct calciothermic reduction of porous calcium titanate to porous titanium

Metallurgical material integration concept was put forward to prepare porous titanium by calciothermic reduction of porous calcium titanate without excessively high temperature and hope to develop short, low-cost and facile fabrication process. The heat generated by calcium vapor reduction of CaTiO3 made titanium particles melt and sinter to interconnect forming porous titanium in Ca-dissolved CaO-CaCl2 molten salt mixtures, as follow.140
