ABSTRACT

The Calcium-aluminate electride thin films on the quartz substrates was coated by sol-gel process. The crystallization of the C12A7 thin film was observed at 800oC and high density C12A7 thin film was achieved on heat treatment at 1,200oC for 1 hour. The reduction heat treatment of C12A7 thin film could be converted from insulator to conductor and the electrical conductivity was 120 S/cm in the C12A7 thin film heat treated at 1,200oC with H2 gas for 48 hours.
