这种强碱在水溶液中可分解成钙和氢氧根离子 用途： 氢氧化钙可用于通过声化学技术制备纳米晶体羟基磷灰石。Ca（OH） 2 可以在固定床反应器中用作松木热解的催化剂。 Calcium hydroxide can be used to prepare nanocrystalline hydroxyapatite by sonochemical technology. Ca (OH) 2 can be used as a catalyst for pine pyrolysis in a fixed bed reactor. Application： Mortar, plasters, cements, gas manufacturing to remove ammonia, in lubricants, water softening, petrochemicals, soil conditioner, paving materialsCalcium hydroxide is used as a flocculant in water and sewage treatment. It is also used in fresh water treatment to raise the pH of the water thereby controlling the corrosion of pipes. It is widely used in the production of calcium stearate. It is an active ingredient in whitewash, mortar and plaster. This compound is also used in the petroleum refining industry for the preparation of additives to oils and in the preparation of dry mixes for painting and decorating. It finds application as an antifungal and antimicrobial preservative for vegetables in storage.
