PROBLEM TO BE SOLVED: To provide a porous body that can be easily given compressive strength through heat curing, but shows a small change in thermal insulation performance even at a temperature exceeding 900°C.SOLUTION: A porous body comprises a silica particle and an alkali collecting material particle. On the surface of the alkali collecting material particle, at least one element A selected from the group consisting of alkali metal and alkaline earth metal is unevenly distributed.
【課題】熱硬化による圧縮強度付与が容易でありながら、９００℃を超える温度にさらされても、断熱性能の変化の小さい多孔質体を提供すること。【解決手段】シリカ粒子及びアルカリ捕集材粒子を含み、アルカリ捕集材粒子の表面にアルカリ金属及びアルカリ土類金属からなる群より選択される少なくとも一種の元素Ａが偏在している、多孔質体。【選択図】図１
