| Abstract: | High purity strontium carbonate is an important and high-value material.It has been widely applying in chemical,electronic and material field because of its outstanding properties.But there are still lots of difficulties in its production,such as the difficulties in controling the preparation process and product quality,the high cost,environmental pollution of the by-products,and so on.This paper focused on the research and application progress in cleaner production of high purity strontium carbonate all over the world.The main cleaner-production technologies for high purity strontium carbonate production such as celestite's reduction method,celestite's double decomposition method,acid-dissolving and NaOH method,roasting-leaching method,Sr(NO3)2 method,SrCl2 method,etc.,were comprehensively described.The technique improvements and pollutants-treatment methods of these technologies were commented as well.The advantages and disadvantages of all the mentioned processes are analyzed.The situation of the production technology of high purity strontium carbonate in China was compared with foreign countries,and the future develop of high purity strontium carbonate production in China was previewed. |
