Abstract
A porous ceramic structure has a porosity of 20% to 99%, and includes one principal surface and another principal surface opposite to the one principal surface. At least one cut is formed from the one principal surface toward the other principal surface. An aspect ratio of a divided portion divided by the cut is greater than or equal to 3.
Claims5
A porous ceramic structure having a porosity of 20% to 99%, comprising one principal surface, and another principal surface opposite to the one principal surface, wherein at least one cut is formed from the one principal surface toward the other principal surface, wherein a depth of the cut is less than a thickness of the porous ceramic structure, and an aspect ratio of a portion divided by the cut is greater than or equal to 3, wherein a thermal conductivity of the porous ceramic structure is less than or equal to 1 W/mK, and wherein the porous ceramic structure has a structure in which fine grains are connected in three dimensions, and a grain diameter of the fine grains is 1 nm to 5 μm.
