Glass in the ZrO2-SiO2 system containing up to 30mol% ZrO2 were prepared by heating the gel made from the mixed solutions of Zr(OC3H7)4 and partial hydrolysed Si(OC2H5)4. As a result, the monolith gel was made from the HCl and water content as 2.7$ imes$10-3 and 8 molar ratio to alkoxide and drying temoperature as 4$0^{circ}C$. Heating rate of dry gel maintained under 0.5$^{circ}C$/min and heating at a temperature as 90$0^{circ}C$ was found to be for making the transparent glass.
