HIGH-PURITY MANGANESE AND METHOD FOR PRODUCING SAME |
摘要 |
<p>High purity manganese having a purity of 3N (99.9%) or more, wherein number of non-metal inclusions with a size of 0.5 µm or more is 50000 or less per 1 g of the high purity manganese. A method for producing high purity manganese, wherein refining is performed using a raw material (secondary raw material) obtained by acid-washing a manganese raw material (primary raw material) so that the produced high purity manganese has a purity of 3N (99.9%) or more, and number of non-metal inclusions with a size of 0.5 µm or more is 50000 or less per 1 g of the high purity manganese. The present invention provides a method for producing high purity metal manganese from commercially available manganese, and aims to obtain high purity metal manganese having a low LPC.</p> |
