Occurrence State and Distribution Law of Titanium in Titanium-containing Cryolite during Preparation of Titanium/Titanium-Aluminum Alloy Powder by Aluminothermic Reduction AITranslate
Abstract AITranslate
Using sodium fluorotitanate as raw material,titanium and titanium alloys were prepared by alu-minothermic reduction at 1150℃.Titanium-containing cryolite was the by-product in the distillation stage of aluminothermic reduction.Based on the diffusion path of titanium-containing cryolite vapor,sampling and analysis of titanium-containing cryolite at different positions in the crystallization zone were carried out.XRF analysis shows that according to the sequence of the flow location of titanium-containing cryolite vapor,the titanium content(calculated as TiO2) of the titanium-containing cryolite samples decreases sharply from 10.38%to 2.70%and then basically stabilizes at 0.16%.XPS analysis shows that titanium in the titanium-containing cryolite exists mainly in the form of TiO2 and TiOS,and the titanium in the two accounts for more than 70%of the total titanium.The titanium-containing cryolite also contains a small amount of titanium nitrides,fluorides and titanium aluminum alloys.The occurrence state of titanium in the titanium-containing cryolite obtained by XRD and SEM analysis is basically consistent with XPS results.
