Fumed Silica분말 소결법을 이용한 석영유리 제조에 소결 온도가 미치는 영향

Abstract

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