▎ 摘　　要

NOVELTY - Photo-catalytic ceramic glaze comprises 40-60 pts. wt. a base material, 1-3 pts. wt. a carbon material, 5-10 pts. wt. a photo-catalytic material and 3-5 pts. wt. an infrared conversion material. USE - Photo-catalytic ceramic glaze used for the inner wall of the chimney (claimed). ADVANTAGE - The photo-catalytic ceramic glaze can realize the function of photo-catalysis under the condition of less visible light, convenient for the nitrogen oxide treatment, especially suitable for the chimney. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing photo-catalytic ceramic glaze, which involves mixing matrix material according to the prescription amount, carbon material, photo-catalytic material, infrared conversion material and solvent, after coating, carrying out heat treatment to obtain the photo-catalytic ceramic glaze.
