A pressure vessel test method was used to fracture tubular specimens of a high-purity, slip-cast fused silica under ten biaxial stress states. The hoop tensile strengths obtained were from 2990 to 4300 psi. The uniaxial compressive strengths ranged from -25,800 to -48,800 psi. Different material lots were employed and strength variation with lot were observed. The modulus of rupture, 5365 psi, also was determined for 34-inch diameter rods.
