產品詳情

詳細信息(中文)：
中文名偏磷酸鈣英文名 CALCIUM METAPHOSPHATE 別名偏磷酸鈣英文別名 CALCIUM METAPHOSPHATE CAS 123093-85-6 化學式 CaO6P2 分子量 198.02 產品用途用作分析試劑偏磷酸鈣 - 簡介開放數據待核驗數據結晶狀和玻璃狀偏磷酸鈣在自然界中分為結晶狀和玻璃狀兩種，結晶狀是白色的，玻璃狀是無色的，結晶狀不溶于水，也不溶于枸櫞酸；玻璃狀在水中能緩慢溶解和水解。結晶體基本上無肥效；玻璃體偏磷酸鈣是一種良好的枸溶性磷肥，含磷量高，用量比普鈣少，最好施在酸性地，肥效持久可以作基肥。制備方法由磷在空氣中燃燒成五氧化二磷，再與磷礦粉在高溫和蒸氣存在下作用而制得。

Name CALCIUM METAPHOSPHATE Synonyms CALCIUM METAPHOSPHATE CAS 123093-85-6 CALCIUM METAPHOSPHATE - Physico-chemical Properties Molecular Formula CaO6P2 Molar Mass 198.02 Use Used as an analytical reagent CALCIUM METAPHOSPHATE - Introduction Open Data Unverified Data crystalline and glassy calcium metaphosphate are divided into crystalline and glassy in nature. The crystalline is white, and the glassy is colorless. The crystalline is insoluble in water or citric acid. The glassy can slowly dissolve and hydrolyze in water. Crystals basically have no fertilizer effect; vitreous calcium metaphosphate is a good citric acid soluble phosphate fertilizer with high phosphorus content and less dosage than calcium superphosphate. It is best applied in acidic ground, and the fertilizer effect can be used as base fertilizer for a long time. The preparation method is prepared by burning phosphorus into phosphorus pentoxide in the air, and then interacting with phosphate rock powder in the presence of high temperature and steam.
