Foreword

The Standard is a modified Russian Standard ΓОСТ17614-1980 "industrial tellurium technical conditions", compared with ΓОСТ17614-1980, The main differences are as follows. --- The standard Te9999, prescribed impurity element Te9995 grades increased bismuth, arsenic, magnesium; --- The standard copper, aluminum, iron, sodium, sulfur impurity element limits stricter than Russian standards, which corresponds to the remaining impurity elements; --- Total amount of impurity elements contained in this standard is lower than the total amount of impurity elements contained ΓОСТ17614 corresponding grades. Instead of the standard YS/T 222-1996 "tellurium ingot." And YS/T 222-1996 "tellurium ingot" Compare this standard main changes are as follows. --- Product grades by the Te-1, Te-2, Te-3 to Te9999, Te9995, Te99; --- The Te9995 grades of Cu from 0.003% to 0.002%, the S content is made 0.005% to 0.004%, the Se-containing Increased from 0.02% to 0.015%; --- Batch of tellurium ingot has been revised; --- Increased production sample extraction, sample preparation methods. This standard by the National Standardization Technical Committee of non-ferrous metals and centralized. This standard by Zhuzhou Smelter Group Co., Ltd. is responsible for drafting.
