Abstract
In the production of an organic-inorganic hybrid glassy material using raw materials which are used in a sol-gel process as starting materials, the present invention relates to a process for producing an organic-inorganic hybrid glassy material, which is characterized in that, there is a heating reaction step between a mixing step and a melting step of the starting materials and there is further an aging step after the melting step. In accordance with the present invention, an organic-inorganic hybrid glassy material satisfying both heat resistance as well as airtight property and low-melting characteristic, which has been believed to be very difficult to produce, is now able to be produced in a very shorter period than before.
