Document Type and Number:
WIPO Patent Application WO/2020/008561
Kind Code:
A1
Abstract:
Provided is a porous material having low thermal conductivity and low thermal capacity. The porous material is equipped with a skeleton provided with a plurality of zirconia particles comprising zirconia. A plurality of pores are formed in the porous material. The plurality of pores have a pore size distribution in which the log differential pore volume reaches a first peak value when the pore size is a first pore size, the log differential pore volume reaches a second peak value when the pore size is a second pore size larger than the first pore size, the first pore size is 0.05-2 µm, and the second pore size is 0.2-50 µm.
