  • High temperature coating on ceramic substrate and non-firing process for obtaining same
    Patent number: 5569427
    Abstract: A process for producing a low porosity, high temperature coating on a porous substrate based on ceramic fibers of refractory compounds. The coating comprises from 30.8 to 41.9 weight % of silica (SiO.sub.2) from a silica sol, from 30.2 to 49.4 weight % of alumina (Al.sub.2 O.sub.3), from 4.0 to 16.3 weight % of silicon carbide (SiC), and from 11.6 to 16.6 weight % of molybdenum disilicide (MoSi.sub.2). The coating has an emissivity of not less than 0.8 and an operating temperature of up to 1500.degree. C. The process is carried out without a firing step and includes the steps of preparing a slurry comprising from 65 to 75 weight % of a silica sol having a content of 20 to 50 weight % of SiO.sub.2 and from 25 to 35 weight % of a mixture of particles of the refractory compounds Al.sub.2 O.sub.3, SiC, and MoSi.sub.
