Product introduction

溶于酸，不溶于水、乙醇和乙醚。有刺激性。四氧化三铁是铁的一种氧化物，其化学式为Fe3O4，相对分子质量为231.53。四氧化三铁是唯一可以被磁化的化合态铁，也是一种偏铁酸盐，可以写作Fe(FeO2)2 的形式。它也可以写成 Fe2O3·FeO 这种氧化物叠加的形式。从这里可以看出，四氧化三铁中两个铁原子是+3价，一个是+2价。富含四氧化三铁的铁矿又称为磁铁矿。四氧化三铁可由铁在氧气中燃烧获得。用于医药、冶金、电子和纺织等工业，以及用作催化剂、抛光剂、油漆和陶瓷等的颜料、玻璃着色剂等。特制的磁性氧化铁可用以制造录音磁带和电信器材。球型四氧化三铁磁粉应用领域如下： 1，生产激光打印机高档墨粉的原料，又能用于生产复印机墨粉（高矫顽力）的原料。 2，磁性密封，可用作机械密封的旋转轴密封。 3，金属、陶瓷、纳米陶瓷、复合陶瓷基片，铁氧体材料。 4，碱性干电池的阴极板，在机械制造业可用于钢铁探伤。 5，抗紫外线材料、微波吸收材料、磁记录材料。 6，磁保健材料，可广泛添加入各类化纤、塑料、橡胶等中，制得各类保健产品和养生产品。 7，建筑结构和混凝土制品的着色。水彩、油漆、涂料等
