[0002] At present, the so-called functional ceramics are mostly porous ceramics with uniformly distributed micropores and low volume density, that is, adding other substances such as nitrides, borides, carbides, silicides and oxides to the ceramic raw materials. It can make the produced ceramics have a certain functionality, and each company has its own special raw material formula and method; there are also nano-scale material powders added to the ceramic glaze to make daily-use ceramics with a nano-structured glaze. For example, the permanent self-cleaning nano-ceramic glaze disclosed in the Chinese patent No. 02115404.X is to add nano-scale material powder to the ordinary glaze to make the ceramic glaze have a nano-structure, so that the ceramic glaze has a hydrophobic and permanent Self-cleaning function, however, this patented technology is only the application of two-dimensional nano, and there are still defects and deficiencies compared with three-dimensional nano
