Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
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. Xu Kaihua, Li Zhi special, Wuya Hui, Zhou Jifeng, Zhang Xiang, Jiang Xiaofeng, Yan pear, Tancui Li.
This standard replaces the standards previously issued as follows.
--- YS/T 673-2008.
Cobalt powder reduction
1 Scope
This standard specifies the requirements for reduction of cobalt powder, test methods, inspection rules, marking, packaging, transportation, storage, quality certificate and contract (or
Orders) content.
This standard applies to cobalt oxalate, cobalt carbonate, cobalt oxide and cobalt-containing material obtained by the reduction of cobalt powder for cemented carbide, diamond products, charge
Electric batteries, ceramics and other industries.
