| description | PURPOSE:To produce the above superconductor having light weight, high stability and excellent superconducting characteristics, by sealing a powdery mixture of a Li salt or a double oxide of Li and Ti and a Ti oxide in a capsule, deaerating in vacuum and baking under hydrostatic pressure under heating. CONSTITUTION:A powdery mixture is produced by mixing (A) an Li salt forming an Li oxide by heating (e.g., Li2CO3) or a double oxide of Li and Ti (e.g., Li2TiO3) and (B) a Ti oxide (e.g., TiO2) at an atomic ratio (Li:Ti:O) of 1+x:2-x:4 (-0.2 |
