A kind of composite is provided, the poor very little of the thermal linear expansion coefficient between the composite and aluminum oxide, and with fully high thermal conductivity factor, compactness and intensity.The densified composite of the present invention includes 37 60 mass % silicon-carbide particle, and each content is below titanium silicide, silicon titanium-carbide and the titanium carbide of the mass percent of the silicon-carbide particle, and the densified composite has less than 1% open porosity.The characteristic of the densified composite includes, and such as 40 570 DEG C of average thermal linear expansion coefficient is 7.2 8.2ppm/K, and thermal conductivity factor is more than 75W/mK, and four-point bending intensity is more than 200MPa. |
