Zirconium oxide-based porous body and method for producing zirconium oxide-based porous body
Provided is a zirconia-based porous body containing an oxide of a rare earth element, the zirconia-based porous body having a pore volume (A) of 0.10 ml/g to 0.40 ml/g when the pore volume (A) is a pore volume having a pore distribution in the range of 30 nm to 200 nm after heating at 1150 DEG C for 12 hours under atmospheric pressure and the pore volume (B) is a pore volume having a pore distribution in the range of 30 nm to 200 nm before heating, and the pore volume (B) is a pore volume having a pore distribution in the range of 30 nm to 200 nm after heating at 1150 DEG C for 12 hours. The retention rate (X) of the pore volume in the range of a pore distribution of 30-200 nm (inclusive) represented by formula [[(pore volume A)/(pore volume B)] * 100] is 25-95% (inclusive).
一种氧化锆系多孔体，包含稀土元素的氧化物，在大气压下，将以1150℃加热12小时后的、细孔分布为30nm以上200nm以下范围内的细孔容积作为细孔容积A，将加热前的细孔分布为30nm以上200nm以下范围内的细孔容积作为细孔容积B时，细孔容积A为0.10ml/g以上0.40ml/g以下，以式[[(细孔容积A)/(细孔容积B)]×100]表示的细孔分布为30nm以上200nm以下范围内的细孔容积的保持率X为25％以上95％以下。
