Photocuring precursor ceramic slurry and preparation method of zirconium-based ultrahigh-temperature ceramic
The invention relates to photocuring precursor ceramic slurry and a zirconium-based ultrahigh-temperature ceramic preparation method, and belongs to the technical field of ceramic materials. Comprising the following steps: mixing a plurality of reactive diluents and photosensitive resin monomers to prepare a premixed solution, adding a photoinitiator, and fully mixing to obtain a photosensitive resin premixed solution; carrying out ball milling on the blocky precursor to obtain precursor powder, adding the powder, a dispersing agent, a coupling agent and an additive into the premixed solution in multiple times, and stirring the prepared photocuring slurry to obtain zirconium-based ceramic precursor photocuring slurry; the method comprises the following steps: designing a three-dimensional model of a complex component by computer-aided design, and then carrying out DLP photocuring 3D printing on a zirconium-based ultrahigh-temperature ceramic biscuit; performing heat treatment on the precursor ceramic biscuit; a compact ZrC/SiC composite ceramic part can be obtained through heat treatment of a sample part prepared from the precursor material through photocuring 3D printing, and an effective way is provided for designing a complex zirconium-based ultra-high-temperature ceramic component to be applied to the field of aerospace.
