Method for preparing ceramic through micro-nano grain-size grading
The invention discloses a method for preparing ceramic through micro-nano grain-size grading and relates to a ceramic preparing method. The method aims at solving the problems that in an existing ceramic powder forming technology, high-density ceramic green bodies and sintering bodies are difficult to obtain, and the comprehensive performance of ceramic materials cannot be effectively promoted. The method includes the steps that firstly, an even mixing solution is prepared; secondly, single-phase or multi-phase ceramic slurry is prepared; thirdly, a ceramic body is prepared; fourthly, sintering densification is conducted, and therefore the ceramic is completed. The method is started with the combination of the problem of micro-nano powder grading in ceramic particle stacking under the centrifugal gel-casting technology, and ceramic materials good in performance are obtained by selecting proper particle size grading proportions. According to the method, the requirement for equipment in the whole preparing technology is low, operation is simple, and the method is suitable for centrifugal gel-casting forming of various ceramic materials through a grading technology.
