3D printing normal-pressure solid-phase sintered silicon carbide ceramic and preparation method thereof
The invention relates to a 3D printing normal-pressure solid-phase sintered silicon carbide ceramic and a preparation method thereof. The preparation method of the 3D printing normal-pressure solid-phase sintered silicon carbide ceramic comprises the following steps: (1) mixing silicon carbide ceramic powder, a boron-containing sintering aid, a carbon-containing sintering aid and a surfactant in a solvent to obtain mixed slurry, and drying, crushing and sieving the mixed slurry to obtain ceramic modified raw material powder; (2) preheating the ceramic modified raw material powder in an internal mixer, then adding a binder and mixing to obtain pug, and cooling and granulating to obtain a granular printing material; (3) molding the granular printing material through an FDM 3D printing process to obtain a silicon carbide ceramic biscuit; and (4) degreasing the silicon carbide ceramic biscuit to remove the binder, and performing normal-pressure solid-phase sintering densification to obtain the 3D printing normal-pressure solid-phase sintered silicon carbide ceramic.
