Several silicon boride phases such as SiB 4, SiB 6, SiB 6-x, SiB 6+x, and Si 11 B 31, were previously reported. Silicon hexaboride (SiB 6 ) has proved to be a potentially useful material because of its high degree of hardness, moderate melting point (2123 K), and low specific gravity.
Rather, it decomposes to silicon and nitrogen and fails to give the improved properties. A major step in developing high density silicon nitride was the accidental discovery in the mid 1970’s that Si 3 N 4 can be sintered if the additives developed for hot-pressed silicon nitride are included in the compact and precautions are taken to limit the loss of silicon nitride.
Abstract: Sintered product exhibiting a relative density of greater than 97% and composed of: more than 92% by weight of silicon carbide, between 0.5% and 8% by weight of an amorphous secondary phase comprising the elements O, Si and one or two

The present invention relates to a method for improving the thermal conductivity of an alumina composite ceramic composition composed of alumina (Al 2 O 3 ) and yttria stabilized zirconia (YSZ). To this end, the present invention is characterized in that the
can be observed that the silicon carbide was sintered to about 0.93 of its relative density by using alumina and yttria as sintering additives. This finding was as a result of a eutectic liquid formed between alumina and yttria at sintering temperature of 1930 C.
