Mullite whisker reinforced alumina-silicon carbide-carbon baking-free refractory material as well as preparation method and application thereof
The invention belongs to the technical field of refractory materials, and particularly relates to a mullite whisker reinforced alumina-silicon carbide-carbon baking-free refractory material as well as a preparation method and application thereof. The corundum or bauxite, the silicon carbide, the calcium aluminate cement, the spherical asphalt, the silicon powder, the aluminum powder and the catalyst are fully and uniformly mixed, the gamma-aluminum oxide and the silicon dioxide are additionally added to serve as raw materials of the mullite whiskers, and the mullite whiskers are subjected to in-situ catalytic growth in a baking-free refractory material matrix and pores under the action of the catalyst at the high use temperature, so that the high-temperature service life of the baking-free refractory material is prolonged, and the service life of the baking-free refractory material is prolonged. The mechanical property and the oxidation resistance of the baking-free refractory material can be obviously improved.
本发明属于耐火材料技术领域，具体涉及一种莫来石晶须增强的氧化铝‑碳化硅‑碳免烧耐火材料及其制备方法和应用。本发明将刚玉或铝矾土、碳化硅、铝酸钙水泥、球状沥青、硅粉、铝粉和催化剂充分混合均匀，额外加入γ‑氧化铝、二氧化硅作为莫来石晶须的原料，在高温使用温度下，由于催化剂的作用，莫来石晶须在免烧耐火材料基质和气孔中原位催化生长，可以显著提升免烧耐火材料的力学性能和抗氧化性能。
