3 Categories and grades that way

3.1 Classification Micron carbonyl iron powder divided into three categories. a) the basis of carbonyl iron. without reducing other post-processing of the original carbonyl iron; b) reduction of carbonyl iron powder. After reducing gas such as hydrogen conducted the carbonyl iron reduction process; c) carbonyl iron phosphate. After phosphating carbonyl iron. 3.2 grades representation MCIP-- ×, MCIP micron level carbonyl iron powder (Microncarbonylironpowder) English name initials; "" represent different categories, including R (Raw) indicates that the underlying carbonyl iron, H (Hydrogenreductive) represents reduction of carbonyl iron, P (Phosphating) represents carbonyl iron phosphide; "×" represent different categories. 4. Technical Requirements 4.1 Designation and chemical composition 4.1.1 micron carbonyl iron powder grades and chemical composition should be consistent with Table 1. ......
