<p>Provided is a composite material having extremely little difference in coefficient of linear thermal expansion with aluminum nitrate, and having sufficient high thermal conductivity, density, and strength. The dense composite material of the present invention contains silicon carbide, titanium silicon carbide, and titanium carbide which are contained in highest contents in order of content, contains 51-68 wt% of silicon carbide, does not contain titanium silicide, and has open pore ratio of 1% or less. The properties of the dense composite material, for example, has average coefficient of linear thermal expansion at 40-570°C of 5.4-6.0 ppm/K, thermal conductivity of 100 W/m·K or more, and four-point bending strength of 300 MPa or more.</p> |
