Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 427-2000 "tantalum pentoxide."
The standards are compared with the YS/T 427-2000 main changes as follows.
--- FTa2O5-1 grades impurity element specified by the 12 kinds increased to 17 kinds;
--- FTa2O5-2 grades impurity element specified by the 12 kinds increased to 17 kinds;
Impurity elements --- FTa2O5-3 grades prescribed by the eight kinds increased to 15 kinds;
--- This standard increased detection method Ta2O5 powder Fisher particle size.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This standard is drafted by. Ningxia Orient Tantalum Industry Co., Ltd., Guangdong Zhiyuan New Materials Co., Ltd, China Nonferrous Metals Industry
Standards and Metrology Institute for Quality.
