| Summary: | The attenuation coefficient of ultraviolet UV light is a critical factor influencing the mechanical properties of photocurable ceramics. Aiming to fabricate high-precision and high-performance ZrO _2 ceramics, this study systematically investigates the impact of the UV attenuation coefficient on the polymerization kinetics of ZrO _2 ceramic slurries. Through linear fitting, the absorption and scattering coefficients of the ZrO _2 slurry were determined as 66 cm ^−1 . By integrating the Beer-Lambert law, we further validated how the UV attenuation coefficient affects the variation in C=C double bond conversion within the cured slurry layers. Additionally, based on Mie scattering theory, although the incident energy was 52 mW cm ^−2 and slice thickness was 50 μm, the curing depth C _d and exposure energy $In{E}_{o}$ is optimal. The ZrO _2 ceramic was formed , in which the sintered sample density was 6.02 g cm ^−3 (99%). |
