硫化亚铁的化学式为FeS(含硫量:36%),硫化亚铁为黑褐色六方晶体难溶于水。可由硫和铁在高真空石英封管内共熔而得,反应方程式为Fe+S→ FeS(条件为加热)。这样制得的硫化亚铁作为化学试剂成本较高,而化学纯试剂硫化亚铁含杂质较多。

⒉Water played an important role in self-ignition of ferrous sulfide. the study showed that the water as required could decreased the initialization self-ignition temperature greatly, but the abundant water could blocked the oxidation of ferrous sulfide.
实验表明,适量的水能够极大的降低硫化亚铁的起始自热温度并对其自热和自燃有正催化作用,而过量的水一则由于阻碍了硫化亚铁与空气中的氧接触难以发生氧化反应,二则由于大量水的存在将硫化亚铁氧化释放的热量吸收,使热量无法得以累积进而使得硫化亚铁不易发生自燃。
