METHOD FOR PRODUCING ZIRCONIUM BORIDE AND FOR SIMULTANEOUSLY PRODUCING CRYOLITE

摘要

A method for preparing zirconium boride and synchronously preparing a cryolite is provided which inc ludes the following step s: Step A: placing aluminum in a reactor , heating the reactor to 700-850 degrees cent igrade, and adding the mixture of fluorozirconate and fluoborate; and Step B: stirring the reactants for 4-6 hours and extracting the upper molten liquid to obt ain a cryolite, wherein the lower subst ance is zirconium boride. The disclosure has the following beneficial ef fects: the new zirconium boride preparation method provided herein is simple in preparation flow and the device used, short in prep aration pe riod and high in reaction ef ficiency, the prepared zirconium boride with m any contact angles has a large specific surface area and contains a controllable amount of aluminum.
