ZIRCONIUM(+4)SILICATE - Preparation Method
Open Data Verified Data
after mixing zirconium quartz and Soda Ash in a certain proportion, it is sent to a high temperature furnace for roasting at about 1100 ° C. After roasting, it is pulverized and then sent to a purification tank, and then the pH value is adjusted to acid with hydrochloric acid, additives are then added to purify titanium, iron and other impurities at 60-80 °c, rinsed with water to remove insoluble salts, and the product is obtained by filtration, drying, and jet grinding.
