Abstract

Abstract 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 I n E o is optimal. The ZrO 2 ceramic was formed , in which the sintered sample density was 6.02 g cm −3 (99%).

光衰减对ZrO2陶瓷固化性能的影响

摘要紫外光的衰减系数是影响光固化陶瓷力学性能的关键因素。以制备高精度高性能的ZrO - 2陶瓷为目标，系统研究了紫外光衰减系数对ZrO - 2陶瓷浆料聚合动力学的影响。通过线性拟合，确定了zro2浆料的吸收和散射系数为66 cm−1。通过对Beer-Lambert定律的积分，我们进一步验证了UV衰减系数如何影响固化浆料层内C=C双键转换的变化。此外，基于Mie散射理论，当入射能量为52 mW cm−2，薄片厚度为50 μm时，固化深度C d和暴露能量I n E o是最优的。制备了zro2陶瓷，烧结样品密度为6.02 g cm−3（99%）。
