摘要
FIELD: chemical engineering and protection of environment. SUBSTANCE: gaseous silicon tetrafluoride is passed through powdered zirconium dioxide at 700-1100 C and resulting products are separated into zirconium tetrafluoride and mixture of formed zircon and unreacted zirconium dioxide. EFFECT: reused zirconium dioxide and silicon tetrafluoride to give valuable zirconium products: high-purity zircon and zirconium tetrafluoride.
