Detailed description of the product:
Purpose: sodium antimonate used as clarifier tube, optical glass and all kinds of advanced glass, flame retardant textiles, plastic products, enamel opal agent, made of opaque paint filler and iron, steel plate acid paint composition of casting; for the identification of sodium ion in chemical analysis. By Regulus pulverizing and sodium nitrate are mixed and heated, air for reaction, followed by nitrate leaching. It can also be mixed by three oxidation of two antimony with hydrochloric acid, and then chlorinated, hydrolyzed and neutralized with excess alkali.
