• The structural change and the adsorption character on heating in vacuo of sepiolite from Kuzuu (Tochigi Pref.) and Korea were studied. By the treatment in vacuo, it has been recognized that a part of sepiolite lattice changes into sepiolite "anhydride" at 200℃ and the 1st. Dehydration of bound water occurs between 200°and 260℃. The dehydration curve treated in vacuo is very sharp. The BET surface area also remarkably decreases when sepiolite treated in vacuo above 200℃. These results show that the channel of sepiolte is sealed when a part of sepiolte transforms into sepiolte "anhydride", as a result, the molecules of adsorbate are not adsorbed into the channel.
