Abstract
The vermiculite sheet is immersed in a silane compound in liquid state so that the silane compound is permeated into the sheet to react with the water absorbed on the whole surface of each thin leave of vermiculite and to form silanol. Thin leaves of vermiculite are strongly bonded with one another through such silanol to form a strong composite sheet.
