Abstract

The quartz glasses were prepared by fumed silica powders sintering method at 1210°C, 1230°C, 1250°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°C. The OH-group and macroscopic pores were removed above 1230°C and highest density and light transmittance were obtained at 1250°C.
