单词 | manganese |
释义 | manganesen. 1. a. A black mineral substance used from ancient times in glass-making and as a component in coloured ceramic glazes, and now in many industrial processes. Also: a coloured ceramic glaze made from this. Also black manganese, †glass-maker's manganese.Black manganese is now known to consist usually of a mixture of various oxides, of which the chief component is manganese( iv) oxide, MnO2 (the mineral pyrolusite). The name manganese is now restricted to the metal (sense 3) in chemical usage; its older application survives only in commercial and industrial use, esp. in ceramics.
