The invention discloses a ceramic product capable of generating negative ions. The ceramic product comprises a green body and a glaze layer covering the surface of the green body. The green body is prepared from the following raw materials by weight: 30-45 parts of albite, 20-25 parts of wollastonite, 10-14 parts of marble, 25-35 parts of kaolin, 12-17 parts of diatomite and 3-6 parts of aluminumsilicate fibers. The glaze layer is prepared from the following raw materials by weight: 20-25 parts of albite, 15-20 parts of wollastonite powder, 17-20 parts of mullite powder, 10-15 parts of quartz, 5-8 parts of talcum powder, 6-10 parts of opal, 4-7 parts of Chinese medical stone, 3-5 parts of tourmaline, 14-18 parts of Zijintu, 9-13 parts of diatomite, 3-4.5 parts of alumina, 2-3.5 parts of magnesium oxide, 2-4 parts of titanium dioxide and 2.5-4.5 parts of silver. The ceramic product of the invention can stably generate negative ions and release a large amount of negative ions, and has good antibacterial effect
