CALCIUM SECONDARY PHOSPHATE ANHYDRIDE PARTICLE AND METHOD FOR PRODUCING THE SAME |
摘要 |
The present invention provides anhydrous dicalcium phosphate particles which satisfies the conflicting requirements of the improvement of handling properties such as high flowability and a small bulk and the improvement of tableting properties at the same time during preparation and a method of producing the same. The method of producing anhydrous dicalcium phosphate by heating water suspensions of a phosphoric acid compound and a calcium compound at 50 to 100°C, comprises the step of:
heating the phosphoric acid compound and the calcium compound at 75°C or higher in advance to carry out a neutralization reaction in the presence of an alkali to obtain agglomerated anhydrous dicalcium phosphate particles. |
