Nanomaterial ceramic spheres, preparation method, and application thereof

A method for preparing nanomaterial ceramic spheres, wherein the nanomaterial ceramic spheres are prepared from raw materials in parts by weight, comprising:

• 1-30 parts of nano-titanium dioxide, 1-30 parts of nano-zirconia, 1-30 parts of nano-tourmaline, and 1-30 parts of kaolin;
• wherein the method comprises steps as follows:
• (1) mixing a first part of the kaolin with water to obtain a resulting kaolin, rubbing the resulting kaolin into soft spheres, and baking the soft spheres to obtain sphere cores;
• (2) mixing a second part of the kaolin, the nano-titanium dioxide, the nano-zirconia, and the nano-tourmaline to obtain a first resulting mixture and performing a pre-mixing on the first resulting mixture to obtain a pre-mixed material;
• (3) mixing the sphere cores, water, an adhesive, and the pre-mixed material to obtain a second resulting mixture and rubbing the second resulting mixture into rounds to obtain a nanomaterial;
• and
• (4) baking the nanomaterial to obtain the nanomaterial ceramic spheres;
• wherein the steps (1) and (2) are not required to be in sequence.
