少し、反応性の高い孤立のＯＨ基が増加することが、赤
外吸収スペクトルの測定から推察される。[Function] Generally, the surface of the metal oxide is hydrated and OH
The group exists. The OH group has a highly reactive isolated O
OH with low reactivity that is hydrogen-bonded with H group and adjacent OH group
The group is believed to be present. When the metal oxide is baked, not only the attached water is desorbed but also the OH groups on the surface react to cause dehydration. In this case, it is inferred from the measurement of the infrared absorption spectrum that the OH groups bonded with hydrogen decrease and the isolated OH groups having high reactivity increase.

揮されると考えられる。Further, even if the same amount of the surface treatment agent is attached to the surface of the metal oxide, in the case of the metal oxide which has not been fired, unreacted OH groups are simultaneously present on the surface. It is considered that the water-repellent effect of the surface treatment agent is reduced. In the present invention, since such unreacted OH groups are reduced, it is considered that the original effect of the surface treatment agent is exhibited.
