The ceramic product comprises the following raw materials by weight percent: 45-50% of bone ash, 1-5% of clay, 8-15% of feldspar, 2-10% of quartz, 15-40% of kaolin, 5-10% of kibushi-clay, 1-3% of a plasticizer and 1-5% of sepiolite mineral nanofiber. The preparation method comprises the following steps: (1) preparing slurry agent; (2) forming; (3) firing; (4) coloring; (5) checking. Compared with the prior art, the ceramic product provided by the invention has the advantages of being good in bone-china texture, relatively high in plasticity in production process, not easy to deform, capable of being prepared into thinner bone-china products, relatively low in cost and relatively little in energy consumption, solving the problem that the land source is short at present, avoiding the problem that no place can be used for burying the dead in the future, and being a way of memorizing relatives.
