The gas desorption properties of carbon based materials coated on inner wall of a cathode ray tube were examined by using a technique of thermal desorption spectroscopy (TDS). This material consists of graphite powder, titanium oxide (TiO<SUB>2</SUB>) powder and water glass. The major outgassing species observed in the temperature range from RT to 500&deg;C were CO<SUB>2</SUB> and H<SUB>2</SUB>O. The major outgassing source was graphite. In order to reduce the gas desorption in the cathode ray tube, the heat treatment with temperature higher than 400-500&deg;C is necessary.<BR>Since the surface morphology of graphite-water glass material was dense, the degassing was insufficient by baking treatment in the atmosphere. On the other hand, the degassing was very easy for graphite-TiO<SUB>2</SUB>-water glass material, because of the porous structure.<BR>The gas adsorption experiments were also conducted. The adsorption amount of H<SUB>2</SUB>O or CO<SUB>2</SUB> increased as the composition ratio of graphite powder. The gas adsorption capacity largely increased by the addition of TiO<SUB>2</SUB> powder into the graphite-water glass material. The enhancement of adsorption capacity is due to that the surface structure became porous and also the effective surface area large by the addition of TiO<SUB>2</SUB> powder.
