METHOD USING SODIUM FLUOROTITANATE AS RAW MATERIAL FOR PREPARING TITANIUM SPONGE

摘要

Provided in the present invention is a method using sodium fluorotitanate as a raw material for preparing titanium sponge. The method comprises the following steps: step A: placing aluminum in a sealed resistance furnace, vacuuming, introducing an inert gas, heating into an aluminum solution; step B: opening a reactor cover, adding an adequate amount of sodium fluorotitanate into a reactor, covering the reactor cover, then detecting for leaks, gradually raising the temperature to 150°C, then vacuuming and continually heating to 250°C; step C: introducing the inert gas into the reactor, continually heating to 900°C, stirring evenly; step D: opening a valve, adjusting the stirring speed, instilling the aluminum solution, and controlling the reaction temperature between 900°C and 1000°C; and step E: opening the reactor cover, removing a stirring apparatus, clearing away NaAlF4 on the upper layer, acquiring titanium sponge. Advantageous effects of the present invention are: a shortened process flow, reduced costs, and environmental benignity, while the final product, titanium sponge, can be used directly in production processes, thus further conserving resources and reducing costs.
