Performance of a Waterproof Glass-Ceramic Coating

Abstract:

The surface of a porous silica ceramic substrate was coated with water impermeable lithium aluminosilicate glass-ceramic layer by sintering a slurry consisted of fine glass powder. The coating was 600~800 microns thick. It is demonstrated that the glass-ceramic coating consists of β-Li₂Al₂Si₃O₁₀ crystallites. The coated sample has an excellent water proof performance. After the coating, both the dielectric constant and loss increase. The coating protected the substrate from ablation under 1700°C.
