Abstract

The quartz glasses were prepared by fumed silica powders sintering method at $1210^{\circ}C$, $1230^{\circ}C$, $1250^{\circ}C$ in air and the effect of sintering temperature on their properties were investigated. The X-ray diffraction pattern, the OH concentration, the light transmittance, the apparent porosity and the density were analyzed. The transparent quartz glass were obtained above $1230^{\circ}C$. The OH-group and macroscopic pores were removed above $1230^{\circ}C$ and highest density and light transmittance were obtained at $1250^{\circ}C$.
