Abstract

The invention provides a technological method for preparing sponge titanium from sodium fluotitanate raw material, comprising the following steps: step A: placing aluminum in an airtight resistance furnace, evacuating, introducing inert gas into the resistance furnace, and heating the aluminum to obtain molten aluminum; step B: opening a reactor cover, adding a proper amount of sodium fluotitanate into the reactor, closing the reactor cover, detecting leakage, slowly heating the reactor to 150° C., evacuating and continuously heating the reactor to 250° C.; step C: introducing inert gas into the reactor, continuously heating the reactor to 900° C., and stirring uniformly; step D: opening a valve, adjusting the stirring speed, dripping the molten aluminum, and controlling the temperature of reaction in a range from 900 to 1000° C.; and step E: opening the reactor cover, removing a stirring device out of the reactor, and eliminating NaAlFat upper layer to obtain sponge titanium.
