摘　　要：根据电子陶瓷行业的需要 ,进行了由石灰石—氯化铵循环法制备高纯CaCO3的研究 ,重点考察了精制除杂条件、氯化铵循环过程。A new technology for preparing ultra-fine and high-purity CaCO_3 by recycling process of limestone and ammonium chloride was researched. The products obtained can satisfy various requirements of the electro-ceramic industry. The effect of purification run,recycling process of ammonium chloride and carbonizing conditions on physico-chemical properties of products was emphatically examined.
