HELIUM GAS SEPARATOR MATERIAL AND METHOD FOR PRODUCING THE SAME |
| 摘要 |
The helium gas separator material includes a base portion and a gas separation portion joined to the base portion. The base portion is composed of a porous α-alumina material which has communication holes with an average diameter of 50 nm to 1,000 nm; the gas separation portion has a porous γ-alumina portion containing a Ni element and a silica membrane portion which is disposed on the inner wall of the communication holes in the porous portion; and the average diameter of pores surrounded and formed by the silica membrane portion is 0.27 nm to 0.60 nm. |
