Preparation method of two-dimensional homogenized mullite corundum high-temperature material
The invention relates to the technical field of high-temperature materials, and discloses a preparation method of a two-dimensional homogenized mullite corundum high-temperature material, which comprises the following steps: 1, selecting a main material and an auxiliary material: 2, respectively preparing a component A and a component B; 3, blending A and B according to the proportion and fully mixing; step 4, molding the mixed mixture; (5) calcining the formed mixture; and 6, cooling to obtain a finished product. A fine-ground low-aluminum material mainly forming a mullite phase serves as a substrate of the two-dimensional homogenized material, a fine-ground high-aluminum material mainly forming a corundum phase is added, and the two-dimensional homogenized material is formed by combining the corundum phase serving as a surface and the mullite phase serving as a point structure after mechanical uniform mixing, forming and sintering. The structure is similar to a long-range ordered and short-range disordered quasi-crystal structure of glass.
本发明涉及高温材料技术领域，且公开了一种二维均化莫来石刚玉高温材料的制备方法，包括以下步骤：第一步：选取主料和辅料：第二步：分别制备A和B组分；第三步：将A和B按照比例调配并充分混合；第四步：将上述混合后的混合物进行成型；第五步：将成型后的混合物进行煅烧；第六步：冷却，成品。通过以形成莫来石相为主的细磨后的低铝材料为主，作为二维均化材料的基底，再加上以形成刚玉相为主的细磨后的高铝材料，共同经机械混合均匀后，成型、烧成，以刚玉相为面、以莫来石相为点结构相结合的二维均化材料。此结构类似于玻璃的远程有序、近程无序准晶体结构。
