Abstract
A porous ceramic structure has a porous ceramic aggregate configured from a plurality of porous ceramic particles, and the ratio of the number of corners at locations where two other porous ceramic particles are facing a corner of a porous ceramic particle with respect to the number of corners of the porous ceramic particles included in the porous ceramic aggregate is 80% or greater.
Claims5
A porous ceramic structure comprising:
- a porous ceramic aggregate including at least a plurality of porous ceramic particles, wherein a percentage of the number of corners at places where a corner of a porous ceramic particle faces two other porous ceramic particles with respect to the number of corners of the porous ceramic particles contained in the porous ceramic aggregate is 80% or more, wherein the porous ceramic particles have an average pore diameter of less than or equal to 500 nm, wherein a thermal conductivity of the porous ceramic particles is less than 1.5 W/mK, and wherein a heat capacity of the porous ceramic particles is less than or equal to 1000 kJ/m3K.
