Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 11071-2006 "Zone Melting Ingot", compared with GB/T 11071-2006, except for editorial modification The changes are as follows. --- The scope is further clarified as "this standard is applicable to the reduction of bismuth ingots and ruthenium single crystals as raw materials, which are prepared by the zone melt purification process. The area is melted ingots. ZGe-0 zone melting crucible is mainly used to prepare high purity germanium single crystal for semiconductor and high purity germanium detector; ZGe-1 The region melting crucible is mainly used for preparing germanium single crystal for infrared optics, germanium single crystal for solar cells, and various germanium-chromium and germanium-silicon alloys. Wait" (see Chapter 1). --- Increased the resistivity of the zone melting ingot at (23 ± 0.5) °C (see 3.2). --- "The difference between the maximum and minimum cross-sectional area of the same bismuth ingot is not more than 15% of the average cross-sectional area" is modified to "the same root zone melting zone" The height difference between the ends of the ingot is no more than 4mm" (see 3.3, 3.3 of.2006). --- "Ingot length 100mm ~ 500mm" revised to "length should be no less than 100mm" (see 3.3,.2006 version 3.3). --- Increased the requirement that the surface of the zone melting ingot should be free of holes (see 3.4 of 3.4,.2006 edition). This standard was proposed by the China Nonferrous Metals Industry Association. This standard is under the jurisdiction of the National Nonferrous Metals Standardization Technical Committee (SAC/TC243). This standard was drafted.

1 Scope

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.
