Abstract
A disk-shaped wafer is described which is based on an inorganic sorbent and a binder, with a thickness of less than 700 microns, which can be obtained by pressing a mixture of the inorganic sorbent, about 20 to 60% by weight of the binder and about 10 to 15% by weight water at a pressure of at least 70 MPa; and calcining the resulting green wafer at temperatures of at least about 500° C. until the water content is substantially removed.
