摘要
Abstract
The cooling rate during the crystallization stage of ammonium heptamolybdate preparation was studied using a multi-functional reactor(fully automatic chemical reactor).The optimal final cooling temperature was experimentally determined.The effects of three cooling modes-rapid cooling,stepwise cooling,and natural cooling—on the crystallization yield,particle size,water solubility,and morphology of ammonium heptamolybdate were investigated.The stepwise cooling mode enabled controllable process conditions,yield-ing products with favorable surface morphology,uniform particle size,high yield,and good water solubility,thereby significantly im-proving production efficiency and economic benefits.关键词
