钼因为熔点高 ,是用于发热元件等的重要金属系耐热材料。其一般加工是采用氢还原的方法用原料矿石制取氧化物的高温工艺。但这种加工工艺会遇到受处理矿石品位限制并产生硫氧化物 (ＳＯ2 )等问题。为此 ,日本东北大学材料工学院目前研制出一种新的工艺方法 ,即通过在水溶液中直 Molybdenum is an important metal-based heat-resistant material used for heating elements and the like because of its high melting point. The general processing is the use of hydrogen reduction method of raw materials ore oxide obtained from the high-temperature process. However, this processing technique encounters problems such as the limitation of the grade of the treated ore and the production of sulfur oxides (SO2). To this end, Japan’s Tohoku University School of Materials Technology is currently developing a new process, that is, through the aqueous solution straight
