A method of coating a ceramic onto a substrate, comprising: selecting said substrate having a top surface; supplying said ceramic having a bottom surface; coating said ceramic onto a selected area on said top surface of said substrate; furnishing at the contact area between said ceramic and said substrate a bonding substance containing a carbide-forming metal which chemically reacts with said ceramic, above a first temperature of below 1500° C., to form a metal carbide capable of bonding to both said ceramic and said substrate, said carbide-forming metal being selected from the group consisting of Au, B, Ir, La, Li, Mn, Mo, Os, Re, Rh, Ru, Si, Th, U, V, W, and mixtures or alloys thereof; and without pressurizing said ceramic and said substrate heating said coated ceramic in contact with said substrate above said first temperature to cause said chemical reaction to occur thereby forming a first bonding layer microscopically substantially perfectly bonding said ceramic to said selected surface of said substrate; said first bonding bonding layer being void-free and microcrack-free and from 100 Angstroms to 0.375 mm thick, and comprising essentially of said metal carbide.
