Composite spinel-corundum refractory material for cremation machine and preparation method of composite spinel-corundum refractory material
The invention discloses a composite spinel-corundum refractory material for a cremation machine and a preparation method thereof, and belongs to the technical field of refractory materials. The composite spinel-corundum refractory material for the cremation machine is prepared from the following raw materials in percentage by mass: 80 to 95 percent of aluminum oxide and 5 to 20 percent of manganese-iron alloy. The prepared composite spinel-corundum refractory material for the cremation machine has the excellent performance of manganese-aluminum sharp crystals and hercynite, and can solve the problems that in the prior art, clay and high-alumina refractory materials for the cremation machine are not ideal in use performance, short in service life and the like; meanwhile, the problems of valence change of Fe/Mn ions, high temperature required by solid-phase sintering, long reaction time and the like when iron oxide and manganese oxide are used as an iron source/manganese source to synthesize hercynite and manganese aluminate spinel materials in the prior art can be solved.
本发明公开了一种火化机用复合尖晶石‑刚玉耐火材料及其制备方法，属于耐火材料技术领域。本发明的火化机用复合尖晶石‑刚玉耐火材料，以质量百分比计，包括以下原料：80～95％的氧化铝、5～20％的锰铁合金。本发明制备的火化机用复合尖晶石‑刚玉耐火材料兼具锰铝尖晶和铁铝尖晶石的优异性能，可以克服现有技术的火化机用粘土质、高铝质耐火材料存在的使用性能不理想、寿命短等问题，同时可以克服现有技术以氧化铁和氧化锰为铁源/锰源合成铁铝尖晶石、锰铝尖晶石材料时存在的Fe/Mn离子变价、固相烧结所需温度高、反应时间长等问题。
