【国家标准】 区熔锗锭

This standard specifies the requirements, test methods, inspection rules, marking, packaging, transportation, storage, quality certificates, and contents of ordering(or contract)of the zone-refined germanium ingot.
This standard is applicable to the zone-refined germanium ingot which is prepared by the zone melting purification process, using reduced germanium ingot and germanium single crystal back to the material as raw material.ZGe-0 zone-refined germanium ingot is mainly used for the preparation of semiconductor and high purity germanium single crystal for high purity germanium detector.ZGe-1 zone-refined germanium ingot is mainly used for the preparation of infrared optical germanium single crystal, solar cells germanium single crystal and various germanium-chromium, germanium-silicon alloy etc.
