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 $1250^{circ}C$.
