This standard replaces GB/T 1422-2004 "铱粉", compared with GB/T 1422-2004, except for editorial changes, major technical changes as follows. --- Removed the description of calcium in the chemical composition of tantalum powder; --- Increased the requirement that the amount of burn loss of tantalum powder should not exceed 0.20%; --- Revised Appendix A for the determination of impurity elements in tantalum powder by inductively coupled plasma optical emission spectrometry, and also can be determined by reference YS/T 364; --- Add Appendix B, Determination of the amount of chalk burning loss by the hydrogen reduction weight method. 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.
