To provide a method of manufacturing a fire-resistant heat-insulating brick low in thermal conductivity relative to a clayey refractory and suitable for a heat insulating material without generating sulfur oxide in baking.
A calcium compound without containing sulfur, a pore imparting agent and water are added in a clay mineral containing SiO2 and Al2O3 as main constituents to be kneaded, obtained slurry is cast, thereafter dried, and baked at a temperature ≥1,200°C. A main crystal phase of the obtained fire-resistant heat-insulating brick is anorthite. In the fire-resistant heat-insulating brick, compressive strength, a rate of residual linear change (1,250°C×12 h) and thermal conductivity (1,000°C) are ≥1.6 MP, ≤1% and ≤0.33 W/(m*K), respectively.
