The effects on the MAP product qualities ofthe presence of seeds, aging and compositions of the reaction mixtures were investigated. This paper also describes the physical and chernical properties ofzeolite MAP. The samples obtained were high crystallinity, high purit怀 having a Si/Al molar ratio of 1.07 1. 13, and had high calcium exchange capacity of290313 mgCaC03/g(zeolite) , fine crystal diameter ofless than 0.4 μm and high oil absorption of83 100 g oiV 100g(zeolite).
