氟磷酸钙

ABSTRACT Yb-doped calcium fluorapatite single crystals were successfully grown by the Czochralski method.

摘 要 用高频感应提拉法生长了掺Yb3+氟磷酸钙晶体，获得了理想的生长工艺参数。

A new ceramic containing fluorapatite and small particles of glass is being used to replace teeth. This ceramic material has the aesthetic look of a natural tooth and causes less wear to opposing teeth than other available materials. Research is even being done on a "ceramic" based gum which is thought to retard the growth of plaque.

一种新型的含有氟磷酸钙以及玻璃小颗粒的陶瓷正用于替代牙齿，用这种陶瓷制成的牙齿，有着和天然牙齿一样的外表，并且具有比由其他用于制作假牙的材料更好的耐磨性，研究人员也正在研制一种陶瓷基牙龈，以阻碍牙菌班的生长。
