Abstract
Disclosed is a highly heat-conductive ceramic material which is basically of SiC-AlN system, comprising SiC, AlN and one or more of metal oxide selected from CaO, BaO and SrO, each in a prescribed amount. The SiC may otherwise be one whose particle surface is coated with the AlN.
Claims7
A highly heat-conductive ceramic material which consists essentially of (i) an amount of silicon carbide not less than about 20% by weight and up to about 85% by weight, (ii) from about 0.1 to about 5% by weight of at least one metal oxide selected from the group consisting of calcium oxide, barium oxide and strontium oxide, (iii) 0 to about 5% by weight of carbon, and (iv) the balance of aluminum nitride.
