production method | in a rare gas atmosphere, 3g of titanium trichloride was placed in an eggplant-shaped flask made of borosilicate glass, the flask was connected to a liquid nitrogen cooling trap nozzle and then to a vacuum pump. When the reaction temperature is higher than 475 ° C., since the generated titanium dichloride undergoes a disproportionation reaction to produce titanium and titanium tetrachloride, it should be noted that the reaction temperature should not be too high. Since a small amount of titanium trichloride is partially vaporized and precipitated at the bottleneck during heating, the precipitate can be often vibrated and returned to the heating section. After the completion of the reaction, a melting seal was performed at a necking prepared in advance in the upper portion of the flask. |
