New Technology for the One-step Preparation of Feed Addttive-Calcium Hydrophosphate
摘要
Abstract
Effects of the amount of H2SO4,Na2SiO3.9H2O and Na2CO3,andreaction temparature on the content of fluorine in feed grade calcium hydrophosphate were studied.The optimum process conditions were determined.Feed grade hydrophosphate with a quality of HG 2636-94 standard was produced by one step defluorination.The yield of phosphrous reached more than 96% from 50％～60％ of traditional two step defluorination. 关键词
