Use | for the preparation of strontium lubricating wax and various strontium salts, but also for improving the drying of drying oil and paint, and sugar beet refined, etc. |
production method | the pure strontium oxide is wetted with a theoretical amount of water, I .e, the heat is released to produce white powder of strontium hydroxide. Further addition of water results in the formation of strontium hydroxide monohydrate, heptahydrate and octahydrate. Strontium hydroxide octahydrate is insoluble. It can also be prepared from a soluble strontium salt reinforced base. Conversion to anhydrous was obtained by heating to 100 °c. The solubility is greater than that of calcium hydroxide, especially at high temperatures. Anhydrous strontium hydroxide is a colorless powder with a relative density of 3.62. Strong hygroscopicity. The SrO was converted by heating to 701 °c. Solubility in 0.8g water 17.4g(20 °c),21.8g(40 °c), 100g (°c). CO2 is absorbed in air and converted to carbonate. |
