Techniques were developed for determining the tensile strength of slip cast fused silica from room +emperature to 1800 deg F. The variation of modulus of rupture of the slip cast fused silica with firing conditions was investigated. A technique for the determination of permeation coefficients for gas flow through the silica was developed using tracer techniques. Basic x-ray-diffraction techniques were applied to the analysis of silica for cristobalite content. Studies were initiated in the fields of optical and electron microscopy and selected area electron diffraction to determine the nature of the cast silica microstructure. Procedures were developed for casting, single piece shell and tube heat exchangers of fused silica (W.L.H)
