Ceramics with tailored pore structure are showing potential applications in some special fields. For fabricating quartz ceramics with orderly-arranged carbon filler, a combination of 3D printing, vacuum suction filtration and sintering was explored to fabricate quartz ceramics with highly-ordered and well-connected big pore channels. The spatial lattice structure in the polylactic acid (PLA) template fabricated by 3D printing together with raw material ratio and sintering temperature has great effect on the properties and pore structure of the porous quartz ceramics. To demonstrate the technical feasibility for fabricating quartz ceramics with orderly-arranged filler, carbon powder was taken as an example and fully filled in the big pore channels of the porous quartz ceramics via vacuum impregnation method. By choosing the quartz ceramics with only highly-ordered and well-connected big pore channels as substrate, quartz ceramics with orderly-arranged carbon filler were successfully obtained.
具有定制孔隙结构的陶瓷在一些特殊领域显示出潜在的应用前景。为了制备具有有序排列碳填料的石英陶瓷,探索了3D打印、真空抽滤和烧结相结合的方法来制备具有高度有序且连通良好的大孔通道的石英陶瓷。通过3D打印制备的聚乳酸(PLA)模板中的空间晶格结构以及原料比例和烧结温度对多孔石英陶瓷的性能和孔隙结构有很大影响。为了证明制备具有有序排列填料的石英陶瓷的技术可行性,以碳粉为例,通过真空浸渍法将其完全填充到多孔石英陶瓷的大孔通道中。通过选择仅具有高度有序且连通良好的大孔通道的石英陶瓷作为基材,成功获得了具有有序排列碳填料的石英陶瓷。
