Abstract : Rocket sled rain erosion and impact evaluation indicated that slip-cast fused silica radomes can satisfactorily survive severe rain erosion environments. Techniques for flame glazing (surface melting) slip-cast fused silica were successful using a high enthalpy arc-plasma flame and an oxyacetylene flame. The effect of NiO, MnO, Co3O4, V2O5, and Cr2O3 additions to fused silica slip on its thermal properties was studied. Felted ceramics techniques were investigated for developing highly refractory structures for hyperthermal applications. Preliminary work was conducted to establish feasibility of forming high temperature resistant felted ceramics. Basically, the felted ceramic process is a modified paper making process. The wood fibers or other organic fibers are used for particulate oxide retention in forming the felt and are subsequently burned out leaving a continuous porosity ceramic structure. (Author)
