Abstract

The invention belongs to the field of preparation of ceramic materials, and particularly relates to a composite ceramic material and a preparation method and application thereof. The preparation method comprises the following steps of using polyvinylpyrrolidone and three-block polyester P123 as template agents, mixing with a precursor of a skeleton formed by butyl zirconate and aluminum chloride, hydrolyzing the precursor under the acid condition, depositing around a template agent aggregate, forming an ordered mesostructure, and removing the template agent by calcining, so as to obtain a nanometer aluminum oxide-zirconium oxide composite material with a mesoporous structure; under the condition of pH (potential of hydrogen) value of 8 to 11, using calcium hydroxide and phosphoric acid as reaction matters to form a nanometer hydroxyapatite crystal nucleus at the surface of the nanometer aluminum oxide-zirconium oxide composite material, so as to obtain the nanometer aluminum oxide-zirconium oxide composite material of which the surface is coated with hydroxyapatite; further performing cold press molding on the composite material, and sintering, so as to obtain the composite ceramic material. The prepared composite ceramic material is an ideal bone replacing repair material.

Description

Technical field [0001] The invention belongs to the field of ceramic material preparation, and specifically relates to a composite ceramic material and a preparation method and application thereof. Background technique [0002] Bioceramics refers to a type of ceramic materials used for specific biological or physiological functions, that is, ceramic materials that are directly used in the human body or directly related to the human body in biology, medicine, biochemistry, etc. As a bioceramic material, the following conditions are required: biocompatibility, mechanical compatibility, excellent affinity with biological tissues, anti-thrombosis, sterilization, and good physical and chemical stability. Bioceramic materials are divided into bio-inert ceramic materials and bioactive ceramic materials. [0003] Bio-inert ceramics mainly refer to ceramic materials with stable chemical properties and good biological compatibility. Such as alumina, zirconia and medical carbon materials. ...
