Effect of Boron Oxide Addition on Microstructure and Mechanical Properties of Slip Cast Fused Silica

Abstract:

Boron Oxide (B₂O₃) was doped in fused silica using slip casting technique. Effects of addition of B₂O₃ on mechanical as well as dielectric properties along with microstructure were studied. It was observed that B₂O₃ acts as devitrification inhibitor by reducing the formation of cristobalite content during sintering of fused silica. Mechanical properties were improved by addition of B₂O₃. Density and flexural strength with (3% by weight) addition of B₂O₃ was 1.89 g/cc and 52MPa respectively.
