<p>PROBLEM TO BE SOLVED: To easily and surely form a uniform colored layer that is free from color shading on the surface of a sintered AlN compact without compromising the intrinsic high thermal conductivity of AlN. SOLUTION: The colored layer composed of a colored ceramic compound, such as SiC, TaN, etc., is formed on the surface of the sintered AlN compact by a sputtering method.</p> |
