Scope
GB/T 11071-2018 is the English-translated version of 区熔锗锭.
GB/T 11071-2018 is the Chinese standard "Zone-refined germanium ingot". Its scope clause reads: This standard specifies the requirements, test methods, inspection rules, marking, packaging, transportation, storage, quality certificate and order form of the zone melting ingot.
(or contract) content. This standard is applicable to the zone melting bismuth ingot prepared by the zone melting purification process using the reduced bismuth ingot and the ruthenium single crystal return material as raw materials.
ZGe-0 area The smelting ingot is mainly used to prepare high-purity germanium single crystal for semiconductor and high-purity germanium detectors; the ZGe-1 region melting ingot is mainly used for preparing infrared optics, and bismuth single crystals for solar cells and various types of bismuth-chromium, bismuth-silicon alloys, and the like. Its clauses include requirements.
