POROUS INORGANIC SINTERED BODY AND METHOD OF PRODUCING POROUS INORGANIC SINTERED BODY
To provide a porous inorganic sintered body having sufficient strength, suppressed variation in the size and volume of pores, and suppressed thermal conductivity.SOLUTION: An inorganic porous sintered body which is characterized in that (a) it comprises, within the body, a plurality of hollow inorganic sintered materials having an average diameter of 0.1 to 2.0 mm and a roundness, expressed as the average of short diameter/long diameter, of 0.75 to 1.00, and (b) it has a variation of bulk density of 95-105%, the variation being obtained by measuring bulk density of four consecutive quadrilaterals having an equal area on the surface of the sintered body, and calculating the variation of bulk density in accordance with the following formula: (maximum or minimum bulk density of each area/average bulk density of the four quadrilaterals)×100.SELECTED DRAWING: Figure 4
【課題】十分な強度を有するとともに、空孔のサイズや空孔量のばらつきが抑制され熱伝導率が抑制された無機多孔質焼結体を提供する。【解決手段】平均直径が０．１〜２．０ｍｍで短径／長径の平均値で表される真円度が０．７５〜１．００である中空状無機焼結物を内部に複数含有するとともに、四つの構成部に分割したときに、下記式（各構成部の嵩密度の最大値または最低値／四つの構成部の嵩密度の平均値）×１００で表される嵩密度のばらつきが９５〜１０５％以下であることを特徴とする無機多孔質焼結体である。【選択図】図４
