HEAT-INSULATING MATERIAL
A heat-insulating material is provided in which thermal conductivity is controlled not to increase and good insulation properties are held even in a high temperature range higher than 1000 DEG C. The heat-insulating material is formed of a spinel porous sintered body having a porosity of 65 to 90 vol. % and represented by a chemical formula XAl2O4 (X-Zn, Fe, Mg, Ni, or Mn) which is arranged such that large pores having a diameter of greater than 1000 [mu]m occupy 25 vol. % or less of the total pore volume, fine pores having a diameter of 0.45 [mu]m or less occupy 5 to 40 vol. % of the volume of the pores having a diameter of 1000 [mu]m or less, at least one pore-diameter distribution peak is within a range of 0.14 to 10 [mu]m, and is formed of sintered particles having a calculated average particle diameter of 0.04 to 1 [mu]m.
