Fleming, J D

Firings were begun on D tensile test slip cast silicon specimens. An average strength of 1960 psi is reported on 15 silicon specimens dried and fired at 2200 deg F for four hours. An elevated temperature testing furnace using silica as the shell and foam silica for insulation was completed. Studies to determine the effects of soaking techniques intended to seal perous silica on strength of the material were continued. Silicon devitrification studies using x- ray diffraction were partially completed, and analysis of results begun. (For preceding period see M-7305.) (J.R.D.)
