High-temperature thermal shock resistant high-purity corundum brick and preparation method thereof
The invention relates to the technical field of corundum refractory materials, and discloses a high-purity corundum brick resistant to high temperature and thermal shock and a preparation method of the high-purity corundum brick resistant to high temperature and thermal shock. The refractory material comprises the following raw material components in parts by weight: 55-65 parts of corundum particles, 25-36 parts of corundum fine powder, 4-12 parts of alpha-Al2O3 micro powder, 0.5-3 parts of alpha-Al2O3 nano powder, a soluble inorganic magnesium salt sintering aid, an adhesive and a dispersing agent. According to the invention, through the grading design of the aluminum oxide powder and the selection of the sintering aid, the sintering temperature is reduced, and the obtained product is a single alpha-Al2O3 phase, has excellent high-temperature thermal shock resistance and can be used in a working environment of more than 1800 DEG C.
本发明涉及刚玉耐火材料技术领域，公开了一种抗高温热震的高纯刚玉砖及其制备方法，所述高纯刚玉砖为单一α‑Al2O3相，按重量份计，其原料组分包括：刚玉颗粒55‑65份、刚玉细粉25‑36份、α‑Al2O3微粉4‑12份、α‑Al2O3纳米粉0.5‑3份、可溶性无机镁盐烧结助剂、粘接剂、分散剂。本发明通过对氧化铝粉体的级配设计，以及烧结助剂的选择，降低了烧结温度，并且所得产品为单一α‑Al2O3相，具有优异的抗高温热震性能，能够用于1800℃以上的工作环境。
