METHOD FOR PRODUCING ZIRCONIUM BORIDE AND FOR SIMULTANEOUSLY PRODUCING CRYOLITE

摘要

Provided is a method for producing zirconium boride and for simultaneously producing cryolite, comprising the following steps: A. placing aluminum in a reactor, heating to a temperature between 700 and 850 °C, adding fluorozirconate and fluoroborate into the reactor; and, B. stirring for 4 to 6 hours, then extracting a molten fluid from the upper layer to acquire cryolite, while the lower layer is zirconium boride. The method is simple, has a short preparation cycle and high reaction efficiency, acquires zirconium boride having large specific surface areas and a great number of contact angles, and allows for controllable aluminum content; the low molecular weight ratio cryolite simultaneously produced is applicable in the aluminum electrolysis industry. Power consumption is reduced, electrolytic efficiency increased, and overall costs reduced.
