Lithium carbonate is an inorganic compound, chemical formula Li2CO3, molecular weight 73.89, colorless monoclinic crystal, slightly soluble in water and dilute acid, insoluble in ethanol and acetone. The thermal stability is lower than carbonates of other elements of the same family in the periodic table, and it does not deliquesce in the air. It can be obtained by adding sodium carbonate to lithium sulfate or lithium oxide solution. It can be converted into acid salt by introducing carbon dioxide into its aqueous solution, which can be hydrolyzed by boiling. It is used as raw materials for ceramics, glass, ferrite, etc., and components are sprayed with silver paste. It is used in medicine to treat mental depression.
Lithium hydroxide is an inorganic compound, the chemical formula is LiOH, it is a white crystalline powder, soluble in water, slightly soluble in ethanol, with strong alkalinity, the pH of 1mol/L solution is about 14, pKb=-0.04, mainly It is used to prepare lithium salt and lithium-based grease, electrolyte of alkaline storage battery, absorption liquid of lithium bromide refrigerator, etc.
Lithium fluoride, an inorganic compound, chemical formula LiF, is an alkali metal halide, white powder at room temperature, slightly soluble in water, insoluble in alcohol, soluble in acid, mainly used in wavelength analysis X-ray fluorescence spectrometer It can also be used as a desiccant, a flux, and can also be used in the enamel industry, optical glass manufacturing, etc.
Cesium iodide (Cesium iodide) is a colorless crystal or crystalline powder, chemical formula CsI. Deliquescence, sensitive to light. It is easily soluble in water, soluble in ethanol, slightly soluble in methanol, and almost insoluble in acetone. Relative density 4.5. Melting point 621 ℃. The boiling point is about 1280 °C. Refractive index 1.7876. irritating. Toxic, the median lethal dose (rat, intraperitoneal) 1400mg/kg, (rat, oral) 2386mg/kg.
Cesium carbonate is an inorganic compound with the chemical formula Cs2CO3. It is a white solid at room temperature and pressure, easily soluble in water, and absorbs moisture quickly when placed in the air. The aqueous solution of cesium carbonate is strongly alkaline and can react with acid to produce the corresponding cesium salt and water, and release carbon dioxide. Cesium carbonate should be sealed and stored dry, and stored separately from acids.
