- the present invention relates to a method of producing an organic-inorganic hybrid glassy material, a method of producing a gel body by a sol-gel method, a melting step by heating, and a method of producing an organic-inorganic hybrid glassy material having at least three steps of ripening step. It is.
- Each process has an important meaning, and it is a necessary process.
- the method of the present invention is fundamentally different from the conventional sol-gel method.
- the conventional sol-gel method after mixing several kinds of sol-gel raw materials, they are stirred at room temperature for several hours and then allowed to stand at room temperature for 2 days to 1 week to obtain a wet gel. Then, it is dried at room temperature to about 100 ° C. for 1 to 3 days to form a dry gel, and if necessary, after washing with powder, washing, and filtration, the temperature is at least 400 ° C. and usually 800 ° C. It is sintered by the above to make a pulp body and a fiber. In the case of a film, it is made into a thin film in the form of a sol, dried and sintered to obtain a thin film. When the gel body is sintered as it is, for example, a transparent material can be obtained, but a low melting point, a material can not be obtained.
- the conventional sol-gel method there is no concept of melting the gel body, and it has entered the sintering process as it is. For this reason, in the conventional sol-gel method, it has been said that the dried gel will not be in a molten state. For example, the concept of meltability is not described at all even in JP-A-2-137737.

- the aging referred to in the present invention is completely different from the aging described by some researchers in the conventional sol-gel method.
- aging does not refer to settling for obtaining a wet gel over 2 days to 1 week, but it is an operation of actively changing the structure of the organic-inorganic hybrid glass after melting to stabilize the glassy substance. Point to For this reason, it is characterized by being treated at a higher temperature than standing conditions, and sometimes under reduced pressure conditions.
- the above-mentioned melting step is not performed, and the dried gel is sintered as it is, so there is no subsequent aging step.
- the aging process is very It is important that even a glassy substance having melting properties can not obtain the desired organic-inorganic hybrid glassy substance without undergoing the subsequent ripening step. If it is simply melted, reactive hydroxyl groups (one OH) remain in the system, and even if it is cooled and solidified, the remaining hydroxyl groups (one OH) cause hydrolysis and one dehydration condensation, and as a result, Can crack or break down and can not obtain good organic-inorganic hybrid glassy material. For this reason, it is an extremely important step to stabilize the reactive hydroxyl group (monoOH) in the glassy material by aging. These points are the points where the present invention and the conventional sol-gel method are largely different.
