seline; background: transparent; text-indent: 2em; font-family: 微软雅黑, 宋体, helvetica, Arial; white-space: normal; line-height: 2em;">seline; background: transparent; font-family: 微软雅黑, "Microsoft YaHei";"> 雄黄在现代工业中有广泛的用途。首先雄黄与雌黄是制取白砒的原料,即砒霜(As2O3)。白砒又是生产半金属砷的原料。高纯度砷可以制作半导体砷化镓。砷还可与铜、铅等金属制成合金,能增加其抗腐蚀性和抗磨性。砷的化合物用于农业上作杀虫剂、除草剂以及木材防腐剂等。另外,在工业中如制革、印染、颜料、玻璃、医药等方面也都有一定的用量。
