ABSTRACT:
The present invention is directed to a cermet material comprising a matrix of aluminum alloy with ceramic particles distributed therein. The cermet is adapted for use as a semiconductor substrate and is manufactured using powder technology procedures. The cermet comprises from about 40 to about 60 volume % of aluminum or aluminum alloy, from an effective amount up to about 10 volume % of binder for enhancing bonding between the aluminum alloy and ceramic particles, and the balance essentially ceramic particles.
