高纯锗多晶材料的制备

Preparation of ultra-pure germanium polyerystalline material

介绍了用国产材料进行锗区熔提纯的制备工艺，借助此工艺已获得净杂质浓度为～１０１０ｃｍ－３量级的多晶材料。

Ultra-pure germanium polycrystalline material with a net impurity concentration of 5 ×1010/cm3 (atoms) has been prepared by the zone refining mathod. All raw materials, reagents and facilities used in the preparation are made in China. The involved techniques are described.
