A study is made of the sealing of slip-cast fused silica by impregnating with ethyl silicate or aluminum chloride solutions, and subsequently pyrolyzing the solutions into silica or alumina by means of arc-plasma flame glazing; or of alternatively sealing the silica by arc-plasma or oxyacetylene-flame spraying of ceramic coatings onto the silica. The thermal shock characteristics of slip-cast fused silica samples are studied, by quenching the samples from 1800 to 70 deg F. The arc-plasma flame melting of alumina is examined. The fabrication of silica radomes by slip-casting techniques is described. The ablative and corrosive effects of an oxy-hydrogen rocket motor exhaust on several plastics are detailed. (T.F.H.)
