Porous ceramic material with cross-scale simulated Haver tube structure, preparation method of porous ceramic material and metal mold
The invention relates to the field of porous ceramic materials, and particularly provides a porous ceramic material with a cross-scale Harvard tube imitating structure, a preparation method of the porous ceramic material and a metal mold. The material comprises a plurality of Harvard tube imitating structure units, the simulated Haver tube structure unit is composed of an organic matter carrier and ceramic loaded on the organic matter carrier; the organic carrier has a hierarchical pore structure; the multi-stage holes comprise through holes and micro holes; the through holes and the micropores are different in direction; the aperture of the through holes is larger than that of the micropores. Compared with the prior art, the porous ceramic material with the cross-scale Harvard-tube-simulated structure has a multi-scale anisotropic pore structure, the micropores and the through holes are interconnected, and the whole structure is similar to a Harvard-tube structure in a dense bone; the porous ceramic material with the cross-scale simulated Haver tube structure has the excellent characteristics of light weight, high strength and the like, and can be used in the fields of biomedicine, aerospace, military protection and the like.
本发明涉及多孔陶瓷材料领域，具体提供了一种跨尺度仿哈弗管结构的多孔陶瓷材料及其制备方法、金属模具。该材料包括若干个仿哈弗管结构单元；所述仿哈弗管结构单元由有机物载体和负载在有机物载体上的陶瓷组成；所述有机物载体具有多级孔结构；所述多级孔包括通孔和微孔；所述通孔和微孔的方向不同；所述通孔的孔径大于微孔。与现有技术相比，本发明的跨尺度仿哈弗管结构的多孔陶瓷材料具有多级尺度各向异性孔结构，且微孔与通孔实现了孔互连，整体结构类似于密致骨中的哈弗管结构；跨尺度仿哈弗管结构的多孔陶瓷材料具有轻质、高强等优异特性，可用于生物医学、航空航天、军事防护等领域。
