A study of mechanical property and corrosion resistance of modified silica glass

Abstract

In this study, alumina added silica glass was fabricated by rapid sintering synthesis. The alumina added samples consist of amorphous matrix phase and dispersed mixed phases including mullite and cristobalite. Dispersed strengthening phases do not induce cracks, instead, improve the overall mechanical properties. At the same time, alumina added sample maintains a similar good corrosion resistance compared with pure silica glass sample. This work provides a modification method to enhance the mechanical property of silica glass without damaging its corrosion resistance.
