四氧化三锰

四氧化三锰用途

【用途一】
用于光学玻璃的制造和低温热敏电阻的制造
【用途二】
主要用于电子工业，是生产软磁铁氧体的原料。软磁铁氧体是由锰、锌、铁的氧化物按一定配比混合后烧结成型制造，具有狭窄的剩磁感应曲线，可以反复磁化，同时其直流电阻率很高，可以避免涡流损失。可用作电子计算机中存贮信息的磁芯、磁盘和磁带，电话用变压器和高品质电感器，电视回扫变压器，磁记录用磁头，电感器，磁放大器，饱和电感器，天线棒等。此外还可用作某些油漆或涂料的色料，含有四氧化三锰的油漆或涂料喷洒在钢铁上比含二氧化钛或含氧化铁的油漆或涂料具有更好的抗腐蚀性能。
【用途三】
用于制陶瓷和玻璃颜料。

四氧化三锰制备

1.焙烧法将金属锰或锰的氧化物、氢氧化物、硫酸盐、碳酸盐、亚硫酸盐、硝酸盐及高锰酸盐在空气中或氧气中，于1000℃灼烧，经冷却、粉碎制得四氧化三锰。如以高纯β-MnO2为原料，于980～1000℃下，在沸腾炉中焙烧，经冷却、粉碎制得γ-Mn3O4产品。其

2.还原法用二氧化锰或水锰矿为原料，先经焙烧成三氧化二锰，再在甲烷气体存在下，于250～500℃进一步还原生成四氧化三锰，经冷却、粉碎制得四氧化三锰成品。其

将电解二氧化锰用雷蒙磨磨成半成品，用4～6mol／L的硝酸于40～60℃下洗涤至pH值6左右，于105℃烘干后，在955～1170℃下焙烧50～130min，炉外真空快冷制得四氧化三锰。或者用软锰矿还原焙烧后用硫酸浸取、净化后用碳酸氢铵进行复分解反应生成碳酸锰，再过滤、分离、干燥、焙烧而得。亦可以300目金属锰为原料，加入铵盐，于60℃反应制得四氧化三锰成品。

3.锰的氧化物、氢氧化物或者硫酸盐、碳酸盐在空气中或者在氧气中灼烧至约1000℃，则容易生成四氧化三锰。电解法制得的二氧化锰(γ-MnO2)于空气中在1050℃下加热可制得四氧化三锰，也可以用四水合硫酸锰于空气中在约1000℃下加热制取。此外，将二氧化锰于氢气流中在200℃下加热也可以制得四氧化三锰。
