Tapecasting Technology for Ceramic Substrates

Alumina ceramic substrates are in great demand in the country for space and electronics industries and they are being imported. Zirconia substrates find application in the fabrication of solid oxide fuel cells (SOFC) and oxygen sensors. CSIRNAL has developed alumina and zirconia substrates. The properties of indigenously developed alumina ceramic substrates exceed the benchmarked specifications. The technology has been transferred to M/s. Carborundum Universal Ltd. (CUMI) and CUMI has successfully
commissioned an industrial scale tapecasting facility for the production of ceramic substrates.
