In addition, what is called attached water, structural water, bound water, or crystal water contained in the crystal structure has been metamorphosed into a smaller structure, and the apparent specific gravity has become smaller, and it is about 10A. The presence of channels that form pores makes it porous, and the presence of amorphous parts increases the specific surface area, making it a more activated material, which allows it to absorb moisture from the air better. It is thought to have the ability to absorb and release odorous substances and the ability to absorb odorous gaseous substances in the air.
