Cesium salt is widely used in the fields of medicine and catalysts in today's industrial production; in the scintillation crystal optoelectronic industry and high-energy physics industry, the chemical formula of cesium sulfate is Cs2SO4. The molecular weight is 361.87. Colorless orthorhombic or hexagonal crystals. The melting point is 1010掳C, and the relative density is 4.243. At 600掳C, it transforms from an orthorhombic system to a hexagonal system. It is soluble in water, insoluble in ethanol and acetone. Cesium sulfate is a colorless rhombic or white needle-like crystal, used as the basic raw material for preparing various cesium salts. Mainly used for analytical reagents, trace analysis of lead, trivalent chromium; special glass; ceramics; catalyst additives. Cesium sulfate has been used for many years as an analytical reagent and certain catalysts. The existing process generally uses cesium carbonate and sulfuric acid to neutralize cesium sulfate, but the process has the following shortcomings in use: 1. The raw material uses cesium carbonate, which is high in cost; 2. In the neutralization preparation process, the product carbonic acid is Weak dibasic acid, the neutralization liquid is acidic, and cesium hydroxide needs to be added to adjust the pH value, which increases the cost, and the carbonic acid is easy to decompose. When the carbon dioxide escapes, the reaction is violent and may cause safety accidents.
