A method of preparing a vacuum insulation panel is disclosed. In the method of the present invention, a plurality of metal oxide-containing compacts, each of which contains less water than the amount of water contained therein at atmospheric equilibrium, are enclosed in a film that retards the passage of moisture therethrough. The film is breached and the metal oxide-containing compacts are positioned in an air-impermeable container at atmospheric pressure. The pressure is reduced in the air-impermeable container, and the air-impermeable container is sealed to form the vacuum insulation panel. Also disclosed is a vacuum insulation panel comprising a plurality of metal oxide-containing compacts disposed in an air-impermeable container, wherein the metal oxide-containing compacts contain less water than the amount of water contained therein at atmospheric equilibrium. |
