Description

Technical field [0001] The invention relates to the technical field of medical materials, in particular to a preparation method of medical imitation porcelain paint. Background technique [0002] Due to the small size effect, surface effect, quantum size effect and macroscopic quantum tunneling effect of nanoparticles, they present characteristics that conventional materials do not possess in terms of magnetism, light, electricity, and sensitivity. Therefore, nanoparticles have broad application prospects in the sintering, catalysis, sensing, and ceramic toughening of magnetic materials, electronic materials, optical materials, and high-density materials. Generally speaking, nano-coatings must meet two conditions: First, the particle size of at least one phase in the coating is within the range of 1-100nm; secondly, the existence of the nano-phase makes the performance of the coating significantly improved or new Function. [0003] After nano products have high-tech meanings, the...
