Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. Instead of the standard YS/T 573-2007 "tantalum powder." Compared with this standard YS/T 573-2007, the main changes are as follows. --- Remove tantalum powder grades FTA42, an increase of FTA150K, FTA170K, FTA200K, FTB85, FTB400 five products Grade tantalum powder grades; --- Products of the chemical composition, physical properties and electrical performance indicators have been adjusted; --- FTC products increased hydrogen content requirements, in addition to outside FTC40 increased liquidity requirements. This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) and focal points. This standard was drafted. Ningxia Orient Tantalum Industry Co., Ltd., Zhuzhou Cemented Carbide Group Co., Ltd., China Nonferrous Metals Industry Standard Associate Institute of Metrology and Quality. The main drafters of this standard. Zhi Road, Luo Guoqing Lin Fu Kun, Chen Xueqing, Zhong Hong, Zhang Jing, SECOND NORTHWEST, Liu silver. This standard replaces the standards previously issued as follows. YS/T 573-2007. Tantalum powder
