Fine ceramic material formed by ceramic precursor skeleton and preparation method and application of fine ceramic material
The invention discloses a fine ceramic material formed by a ceramic precursor skeleton and a preparation method and application of the fine ceramic material, and relates to the technical field of ceramics. The preparation method comprises the following steps: dipping porous foam into ceramic precursor slurry to obtain a porous ceramic skeleton blank; performing pyrolysis treatment on the porous ceramic skeleton blank body to obtain a porous ceramic skeleton; filling the porous ceramic skeleton with ceramic powder slurry to obtain a high-density ceramic green body; and sintering the high-density ceramic green body into the fine ceramic material through a sintering process. By taking porous foam as a template, a ceramic skeleton is prepared by a method of dipping a template and then conducting pyrolyzing. The matrix ceramic powder is injected into the skeleton, and curing and sintering are conducted to prepare the composite ceramic sintered body. The reinforced phase of the ceramic sintered body is a morphology-controllable ceramic skeleton, the microstructure of the sintered body is regulated and controlled, and the ceramic performance is improved. The ceramic skeleton is prepared by pyrolyzing a ceramic precursor, and the matrix ceramic is added in a powder injection manner, so that the composite ceramic is controllable in component and microstructure.
本发明公开了一种通过陶瓷前驱体骨架成型的精细陶瓷材料及其制备方法和应用，涉及陶瓷技术领域。制备方法包括：将多孔泡沫浸渍到陶瓷前驱体浆料中，得到多孔陶瓷骨架胚体；对多孔陶瓷骨架胚体进行热解处理，得到多孔陶瓷骨架；在多孔陶瓷骨架内填充陶瓷粉体浆料，得到高密度陶瓷坯体；通过烧结工艺将高密度陶瓷坯体烧结为精细陶瓷材料。以多孔泡沫为模板，通过浸渍模板后热解的方法制备陶瓷骨架；将基体陶瓷粉体注入骨架固化后，烧结制备复合陶瓷烧结体。陶瓷烧结体的增强相为形貌可控的陶瓷骨架，调控了烧结体的微观结构，实现陶瓷性能提升。陶瓷骨架由陶瓷前驱体热解制备、基体陶瓷由粉体注入的方式加入，使得复合陶瓷成分可控，微观结构可控。
