Abstract

The invention belongs to the technical field of special functional ceramics, and particularly relates to photocurable fused silica slurry and a preparing method and application thereof. The photocurable fused silica slurry is prepared from, by volume percentage, 50-70% of grading quartz powder and 30-50% of photo-cured resin with the addition of UV dispersant, an anti-settling agent, a defoaming agent and photoinitiator, and the sum of the volume percentage of the grading quartz powder and the photo-cured resin is 100%. By strictly controlling the process parameters such as usage amount matching, charging sequences and the ball milling time, the photocurable fused silica slurry which is high in solid content (the solid content is larger than or equal to 50 vol.%), low in viscosity (the viscosity is smaller than 3000 mPa.s) and high in stability is prepared. The preparing method is simple and easy to implement, and the prepared fused silica slurry is used for forming individual, complicated, specialized and high-difficulty special-shaped precise components.

Description

technical field [0001] The invention belongs to the technical field of special functional ceramics, and in particular relates to a light-curable quartz ceramic slurry and a preparation method and application thereof. Background technique [0002] In recent years, with the increasing demand for ceramic components such as special-shaped functional structural components, tailor-made functional components in the biological field, and gradient frequency-selected ceramic materials in the high-end manufacturing industry, it is difficult to design and manufacture artificial functional gradient structures to achieve single or homogeneous materials. The excellent performance achieved has always been a research hotspot in the field of materials science, but the current technological means cannot give full play to the excellent characteristics of designable functionally graded materials. Although new ceramic molding technologies continue to emerge, none of them can get rid of the constr...
