    • A method for producing optical glass, which comprises charging a mixed solution capable of forming a high-silica-content gel by hydrolysis reaction into a vessel, the inner wall face of which is composed of a material unwettable to the mixed solution, such as a fluorocarbon resin or silicone resin, causing gelation of the mixed solution in the vessel, drying the obtained gel, and heating and sintering the obtained dry gel. When electrodes are placed in the mixed solution at the gelation step and an electric voltage is applied, the time required for formation of the gel is shortened. Furthermore, at the gel-drying step, if the amount of materials evaporated from the gel is detected or the weight of the gel is measured, the detected amount of the evaporated materials or the change of the weight of the gel is fed back to a factor regulating the drying speed, such as the drying temperature to control the drying speed to an appropriate level.
    • 一种光学玻璃的制造方法,其特征在于,将能够通过水解反应形成高二氧化硅含量凝胶的混合溶液装入容器内,该容器的内壁面由不能混合的溶液的材料构成, 氟树脂或有机硅树脂,使混合溶液凝胶化,容器干燥,加热烧结得到的干凝胶。 当在凝胶化步骤中将电极置于混合溶液中并施加电压时,形成凝胶所需的时间缩短。 此外,在凝胶干燥步骤中,如果检测到从凝胶蒸发的材料的量或测量凝胶的重量,则将检测到的蒸发材料量或凝胶重量的改变反馈至 调节干燥速度的因素,如干燥温度,将干燥速度控制在适当的水平。
