preparation example Construction
[0023] The preparation method of the coating material in the present invention: the present invention can directly mix zirconia particles, magnesia particles and glass components, silicon dioxide particles and colloidal silica, and make slurry for coating, or pre-coat the zirconia Granules, magnesia particles, glass components, and silica particles are mixed, and then the sintered body obtained by pulverizing and sintering is used as a coating material mixed with the pulverized pulverized product and colloidal silica. The slurry of the coating material preferably contains water-soluble macromolecules such as methyl cellulose as an organic binder, and the content of the organic binder accounts for 0.5-10% by weight of the inorganic solid component in the slurry, more preferably in 0.5% by weight. 1-5% by weight.
[0024] The coating method of the coating material of the present invention: coating on the platinum material in the form of slurry, coating the slurry on the platinum...
