The current preperation methods of strontinum carbonate from celesite are carbon reduction method and double decomposition method.

中青石资源十分丰富,但矿石品位低、杂质含量高,需经选矿除杂后才能作生产碳酸锶的原料。

Fluorapatite was prepared by adopting double decomposition method, and the properties were characterized by XRD, XPS and antibiotic testing.

采用复分解反应制备了石,对有、无锌离子的石进行结构和性能比较。
