高纯碳酸锶粒径的评价方法与生产控制手段

Evaluation methods and production control measures for particle size of high purity strontium carbonate

介绍了直接观察法、沉降法、激光法、小孔通过法、吸附法、压缩密度法等几种高纯碳酸锶颗粒粒度的评价方法。指出通过控制化合加料速度、热解及陈化可以控制产品粒径和质量,为高纯碳酸锶生产中的粒径控制提供了多种方法。评价方法与生产控制手段,为高纯碳酸锶生产中的粒径控制提供了多条途径。

The conventional evaluation methods of paritcle size of high - purity strontium carbonate, such as direct obseration method,settling method,laser method,small hole pass method,adsorption method and compress density method are introduced. And the production control measures of particle size such as controlling adding speed of reactant, controlling pyrolysis and ageing process etc. are also provided.
