.比較例1参照)。Conventionally, amorphous calcium silicate hydrate in the form of a tree or amorphous calcicum silicate hydrate formed using a filter press or the like is placed in an autoclave, and after the apparatus is placed, a hydrothermal reaction is performed. A feature of the present invention is that calcium silicate hydrate is introduced into hot water or hot alkali which has been set at a reaction temperature in advance for reaction. Fortunately, according to the method of the present invention, the reaction time of crystalline calcium silicate hydrate, which took a long time to synthesize, can be drastically reduced! This is what iJI was able to do. For example, when praying for tobermorite crystals, the conventional method uses 3% at 180C.
In actual practice, it was possible to obtain tobermorite with good crystallinity in 1 hour (*1 Example 1).

The temperature of the hot water or alkaline water S* to be heated is a degree to carry out the water chicken reaction.The membership fee is specified by the IC regulations, therefore, the ILIL range is 100 to 400.
This is the range of C. - In Kameirashi, where the water chicken reaction temperature is below 100CJjL, the skin becomes too thin and the effect of the present invention cannot be fully realized.On the other hand, at 400℃ or higher, the reaction equipment becomes large-scale and expensive. In addition, at temperatures above 400°C, the effect of accelerating the crystallization rate is small, even though the degree of haze is increased1.
