Instead of the standard YS/T 673-2008 "reduction of cobalt powder." This standard YS/T 673-2008 compared to the main changes are as follows. --- Modified grade division and representation of products; --- Modify the various grades of carbon content indicators; --- Modify various grades oxygen content indicators; --- Modified Ni, Cu, Fe, Zn, Cd, Mn, Na, Si, S content of impurity elements of chemical grade the first level of the product; --- Fisher particle size by the three levels of re-divided into five levels; --- Chemical composition of a new level. This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized. This standard was drafted. High-tech Co., Ltd. Shenzhen Grammy, Jinchuan Group Co., Jingmen Grammy New Material Co., Ltd., Jiangxi Grammy resource recycling Limited. The main drafters of this standard.
