INORGANIC POROUS SINTERED COMPACT AND METHOD FOR PRODUCING THE SAME
PROBLEM TO BE SOLVED: To provide an inorganic porous sintered compact, in which the size of a hole and dispersion of porosity are controlled and heat conductivity is controlled while having sufficient strength.SOLUTION: An inorganic porous sintered compact comprises a sintered compact of a hollow-shape inorganic particle, the average diameter of which is 0.1-2.0 mm and whose roundness represented by the average of (minor axis)/(major axis) is 0.75-1.00. The inorganic porous sintered compact has a plurality of isolated pores dispersed thereinside. When the inorganic porous sintered compact is divided into four configuration parts, the variation of bulk density represented by the following formula is 95-105% or less: ((a maximum or minimum value among the bulk densities of configuration parts)/(an average value of the bulk densities of four configuration parts))×100. A method for producing the inorganic porous sintered compact includes: a degreasing step of conducting desired formation to a coated granular body having an inorganic powder coating layer on an inorganic material-made spherical matter, and then of removing the inorganic material-made spherical matter; and a step of conducting a baking treatment to form the sintered compact.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の提供。【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である中空状無機粒子の焼結体からなり、内部に独立気孔を複数分散含有するとともに、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％以下である無機多孔質焼結体。有機物質製球状物上に無機粉末コーティング層を有するコート顆粒に対し、所望の形状に成形し、前記有機物質製球状物を除去する脱脂工程を施した後、焼成処理して焼結体を形成する焼成工程を施すことにより得られる無機多孔質焼結体の製造方法。【選択図】図４
