| abstract | Disclosed is a cycled preparation method that uses mixture of sodium-based titanium and boron fluoride salts as intermediate raw material and produces titanium boride and simultaneously sodium cryolite. The method comprises the following steps: A) adding hydrofluoric acid to boric acid or boron anhydride, then adding sodium carbonate solution, and concentrating and crystallizing to obtain sodium fluoborate; adding hydrofluoric acid to titanium iron ore concentrate, and adding sodium carbonate and sodium hydroxide to obtain sodium fluorotitanate; B) mixing the sodium fluoborate and sodium fluorotitanate, and reacting with aluminum to obtain titanium boride and sodium cryolite; C) extracting the sodium cryolite, putting into a rotary reactor together with concentrated sulfuric acid to react and produce hydrogen fluoride gas, sodium sulfate, and sodium aluminum sulfate, collecting the hydrogen fluoride gas, and dissolving in water to obtain hydrofluoric acid aqueous solution; D) recycling the obtained hydrofluoric acid aqueous solution for use. The present invention recycles the byproduct, sodium cryolite, simplifies the preparation process for titanium boride, lowers the technical requirements for titanium boride preparation and the comprehensive production cost, enhances production efficiency, and reduces environmental pollution. |
