锆英砂

锆英砂（锆英粉）用于耐火材料（称锆质耐火材料，如锆刚玉砖，锆质耐火纤维），铸造行业铸型用砂（精密铸件型砂），精密搪瓷器具，此外也用于玻璃、金属（海绵锆）以及锆化合物（二氧化锆、氯氧化锆、锆酸钠、氟锆酸钾、硫酸锆等）的生产中。

Zircon sand (zircon powder) is used in refractories (such as zirconium corundum bricks and zirconium refractory fibers), Casting sand for casting industry (precision casting sand), precision ceramic appliances, and also in the production of glass, metal (sponge zirconium) and zirconium compounds production (zirconium dioxide, zirconium oxychloride, sodium zirconate, potassium fluorozirconate, zirconium sulfate, etc.).
