概要
- 論文の詳細を見る
Positron annihilation lifetime technique was applied to non-destructive analysis of porous materials such as zeolite, porous glass, and zirconia. The technique can detect sensitively a size, a number and a size distribution of a open space in materials in a wider range of 0.1∿10 nm than those obtained by nitrogen adsorption or mercury porosimetry.
