Properties of Quartz Momentive Tech

网页Mechanical Properties Mechanical properties of fused quartz are much the same as those of other glasses. The material is extremely strong in compression, with design compressive strength of better than 1.1 x 10 9 Pa (160,000 psi).. Surface flaws can drastically reduce the inherent strength of any glass, so tensile properties are greatly influenced by these defects.
