PROBLEM TO BE SOLVED: To provide a heat resistant member having a low heat capacity and high corrosion resistance to alkali, at a low cost. SOLUTION: This heat resistant member contains 10-35 pts.wt. of high- alumina fiber having a >=70 wt.% alumina content, 65-90 pts.wt. of α-alumina particles having a 1-45 μm average particle size, 4-12 pts.wt. of colloidal silica (expressed in terms of solid content) and 0.1-8 pts.wt. of an organic binder (expressed in terms of solid content), and has a 0.4-1.2 g/cm<3> density. |
