NOVELTY - An environment-friendly negative ion ceramic tile comprises a ceramic body, and a glaze. The ceramic body comprises diatomaceous earth, clay, sandstone, tourmaline powder, black phosphorus, and graphene. The glaze comprises albite powder, talc powder, silica sol, microlite, glass-ceramics, rare earth materials, graphene, and carnelian powder. USE - An environment-friendly negative ion ceramic tile. ADVANTAGE - The ceramic tile has excellent anion release capability, has an anion release that can improve air quality, improves health of human body, and improves immunity of human body. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the environment-friendly negative ion ceramic tile, comprising: (A) ball-milling raw materials of a ceramic body to obtain a slurry; (B) sieving the slurry, filtering to obtain a mud cake, and aging for 7-10 days to obtain a ceramic blank; (C) ball-milling raw materials of a glaze with a fineness of 250 meshes; and (D) coating the ceramic body with the glaze, heating to 350-400 degrees C, and sintering under nitrogen atmosphere at 1280-1300 degrees C.
