摘　　要：阐述磷矿中氧化钙、倍半氧化物、氧化镁、氧化钾、氧化钠及酸不溶物对磷酸生产的影响,磷酸中镁与氟对磷铵生产过程的影响,以及磷酸中金属离子对磷铵产品质量的影响。介绍克服杂质对磷酸、磷铵生产影响的措施,包括一系列物理和化学净化除杂方法,可使产品质量符合标准要求。The effects of calcium oxide, sesquioxide, magnesium oxide, potassium oxide, sodium oxide, and acid non-soluble substance in phosphate rock on production process of phosphoric acid, and effects of magnesium and fluorine in phosphoric acid on the production of phosphate ammonium, as well as effects of metal ions in phosphoric acid on quality of phosphate ammonium products are elaborated. The control measures corresponding to these influences are introduced including a series of physical and chemical methods to purify the impurities, which can make the product quality conforms to the standard.
