The fine particles were mixed and dispersed well. The pH of the dispersion was adjusted, and the dispersion was poured into a container to form a gel, thereby creating a wet gel. The wet gel was dried to prepare a dry gel.

。The vaginal dry gel was then sintered and vitrified. (Figure 2)
The sintering program is different from normal transparent glass manufacturing methods. That is, the temperature was gradually increased to close the internal pores, and then the temperature was increased by 20° C., held for 60 minutes, and then slowly cooled.

(Specific gravity: 2.63) (In this case, after the pore-closing treatment, the temperature was raised to 100°C and held for 2 hours.) Even when the surface of the opaque glass above was wetted with water, it was confirmed that it maintained its opacity. did.
