Low-thermal-conductivity chromium-zirconium-corundum brick for hazardous waste treatment and preparation method thereof
The invention belongs to the technical field of refractory materials, and particularly relates to a low-heat-conductivity chromium-zirconium-corundum brick for hazardous waste treatment and a preparation method of the low-heat-conductivity chromium-zirconium-corundum brick. The low-heat-conductivity chromium-zirconium corundum brick with high compressive strength, low heat conductivity coefficient and good thermal shock resistance stability is obtained by mixing, pressing, drying and firing raw materials including fused white corundum powder, zirconium oxide micro powder, chromium oxide micro powder, aluminum oxide micro powder, metakaolin, iron oxyhydroxide modified diatomite and modified water glass. The added hydroxyl ferric oxide modified diatomite and sodium tetraborate modified water glass can generate chemical bonding with other raw materials in the mixing process to form good interface bonding, so that the mechanical property of the product is improved.
本发明属于耐火材料技术领域，尤其涉及一种危废处理用低导热铬锆刚玉砖及其制备方法。通过以电熔白刚玉粉、氧化锆微粉、氧化铬微粉、氧化铝微粉、偏高岭土、羟基氧化铁改性硅藻土和改性水玻璃为原料，经混合、压制、干燥、烧制后得到具有高抗压强度、低导热系数、良好抗热震稳定性的低导热铬锆刚玉砖，加入的羟基氧化铁改性的硅藻土和四硼酸钠改性的水玻璃使其在混合过程中能够与其他原料间产生化合键合，形成良好的界面结合，从而提高产品的力学性能。
