| Abstract: | New compound,La 2-x Ag x CaCu 2O 6 has been prepared by high temperature solid phase reaction. And its synthesizing conditions have been found. The research into its structure indicates that it has the typical crystal structure of La212 type compounds: La and Ag occupy the position of 4e,and Ca occupies that of 2a. The relationship between the resistance of La 1 65 Ag 0 35 CaCu 2O 6 and temperature has been characterized by metallic behavior. |
| Keywords: | La212 Type Compound La 2-x Ag x CaCu 2O 6 synthesis metallicity |
