Composite spinel mullite ceramic refractory material and preparation method thereof
The invention relates to the field of composite materials, in particular to a composite spinel mullite ceramic refractory material and a preparation method thereof. The composite spinel mullite ceramic refractory material is prepared from, by weight, 9-25 parts of caustic calcined magnesia powder, 50-100 parts of industrial aluminum oxide and 8-20 parts of quartz powder. The preparation method comprises the following steps of: weighing the components according to the ratio, mixing well, adding the mixture into a submerged arc furnace, heating and melting for 5-15 minutes by an electric arc at 2200-2500 DEG C, then inclining the submerged arc furnace, pouring the melted product into a water tank, quickly cooling the product, and fishing out and drying the product. An existing composite refractory material sagger prepared by using spinel and mullite as raw materials is poor in corrosion resistance in the sintering process of a lithium battery positive electrode material. By changing the raw materials and limiting the amount of each component in the raw materials, the finally provided composite spinel mullite ceramic refractory material not only maintains the original fire resistance and thermal shock resistance, but also has enhanced lithium ion corrosion resistance.
本发明涉及复合材料领域，尤其是涉及一种复合尖晶石莫来石陶瓷耐火材料及其制备方法，所述复合尖晶石莫来石陶瓷耐火材料的原料包括以下重量比的成分：轻烧镁粉9‑25份、工业氧化铝50‑100份和石英粉8‑20份。其制备方法包括以下步骤：按照配比称取各成分，混匀，加入矿热炉，在2200‑2500℃电弧加热熔融5‑15分钟，然后倾斜矿热炉倒入水槽中快速冷却，捞出干燥。现有用尖晶石和莫来石做原料制备的复合耐火材料匣钵，在锂电池正极材料烧结过程中抗腐蚀性差，本申请通过改变原料，并限定原料中各成分的用量，最终提供的复合尖晶石莫来石陶瓷耐火材料中不仅保持了原耐火性和抗热震性能，且增强了抗锂离子耐腐蚀性能。
