Abstract
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.
