Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 11070-2006 "reduction germanium ingot." This standard compared with GB/T 11070-2006, the main technical changes as follows. --- Remove normative references GB/T 1551, increase GB/T 26074, YS/T 602; --- Raw material requirements amended as "raw materials for the production of germanium ingot should be consistent with the provisions of GB/T 11069 high purity germanium dioxide"; --- Preparation of the regional germanium ingot electrical performance requirements amended to "RGe-0 reduction germanium ingot by directional crystallization and 6 after zone melting obtained after purification Melting germanium ingot, the conductivity type is N type, the resistivity greater than 47Ω · cm portion should account for more than 60% germanium ingot length or By both supply and demand sides to determine "; --- Remove "Dimensions"; --- The 5.4.1 "RGe-0 product batch is not greater than 50kg" to "product weight not more than 100kg." This standard is proposed by China Nonferrous Metals Industry Association. This standard by the National Non-ferrous Metal Standardization Technical Committee (SAC/TC243) centralized. This standard was drafted unit. Nanjing, germanium technology limited liability company, Yunnan Lincang Xin Yuan Germanium Industry Co., The main drafters of this standard. Liu Xinjun, universal Kun, Ke Zun Bin. This standard replaces the standards previously issued as. --- GB/T 11070-1989, GB/T 11070-2006. Germanium ingot reduction
