钼在国民经济建设中的作用1778年,瑞典化学家发现了钼,用硝酸分解辉钼矿,制得了各种钼盐。1781年,瑞典人用炭还原氧化钼制得了金属钼。19世纪,钼作为合金添加剂加入钢中,提高了钢的强度,钼钢在空气中冷却后,增加了钢的硬度。1910年,发现炮钢中加入钼后,具有优良的性能。从此,钼作为重要的合金元素在冶金工业上得到了广泛地应用。
The Role of Molybdenum in National Economic Construction In 1778, Swedish chemists discovered molybdenum, decomposing molybdenite with nitric acid to produce various kinds of molybdenum salts. In 1781, the Swedes made molybdenum by reducing the molybdenum oxide with carbon. In the 19th century, molybdenum was added to the steel as an alloying additive to increase the strength of the steel. After the molybdenum steel was cooled in the air, the hardness of the steel was increased. In 1910, it was discovered that the addition of molybdenum to gun steel has excellent performance. Since then, molybdenum has been widely used in the metallurgical industry as an important alloying element.
