Manganese metal is very useful, if in steel join 2.5-3.5% of manganese, then water-heating low manganese steel simply brittle like glass, as a knock is broken.
锰是十分有用的金属，如果在钢中加入2.5—3.5%的锰，那么所制得的低锰钢简直脆得象玻璃一样，一敲就碎。
The XRD studies indicates that manganese slag is mainly composed of crystallized slag and some glass phases and this is the main reason of its low activity.
由XRD研究知锰矿渣主要由结晶矿渣和部分玻璃相所组成，这是其活性较低的主要原因。
