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

采用反应制备了氟磷灰石,对有、无锌离子的氟磷灰石进行结构和性能较。

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

中国天青石资源十丰富,但矿石品位低、质含量高,需经选矿才能作为生产碳酸锶的原料。
