Zirconia porous body and manufacturing method thereof

摘要

A zirconia porous body with excellent stability of heat resistance is manufactured. This relates to a zirconia porous body having peaks at pore diameters of 8 to 20 nm and 30 to 100 nm in a pore distribution based on the BJH method, with a total pore volume of 0.4 cc/g or more, and to a zirconia porous body having a peak at a pore diameters of 20 to 110 nm in a pore distribution based on the BJH method, with a total pore volume of 0.4 cc/g or more.
