摘要:

彩色氧化锆陶瓷具有鲜艳色彩、高折射率、耐磨损、耐腐蚀及对人体无毒等优点, 被广泛应用于电子、装饰等领域。本研究采用共沉淀法合成了平均粒径为15.9 nm的立方相Ce:8YSZ纳米粉体。以经过800 ℃煅烧4 h的粉体为原料, 通过两步烧结技术制备了具有高光学透过率和高红色度的Ce:8YSZ透明陶瓷,并系统研究了空气预烧温度对红色Ce:8YSZ透明陶瓷微观结构、直线透过率和色度的影响。当预烧温度从1200 ℃升高到1300 ℃时, Ce:8YSZ陶瓷的平均晶粒尺寸从0.3 μm增大到2.2 μm, 同时相对密度从87.2%增加到97.1%。经过1275 ℃空气预烧2 h并结合1700 ℃热等静压烧结3 h所得的Ce:8YSZ透明陶瓷表现出最佳的光学质量和最大的红色度值, 在700 nm处的直线透过率为47.6%, 红色度为52.0。

Abstract:

Color zirconia ceramics are widely used in electronics and decoration fields due to their bright colors, high refractive index, wear resistance, corrosion resistance, and non-toxicity to the human body. Cubic cerium doped 8% yttria mol percent stabilized zirconia (Ce-doped 8YSZ) nano-powder with average particle size of 15.9 nm was synthesized by co-precipitation method. Using the powder calcined at 800 ℃ for 4 h as starting material, red zirconia transparent ceramics with high optical transparency and high redness value were prepared by two-step sintering method. Influences of pre-sintering temperature on microstructure, in-line transmittance and color performance of the red Ce-doped 8YSZ ceramics were studied. As the pre-sintering temperature increases from 1200 ℃ to 1300 ℃, average grain size of the ceramics increases from 0.3 μm to 2.2 μm and the relative density increases from 87.2% to 97.1%. The Ce-doped 8YSZ ceramics pre-sintered at 1275 ℃ for 2 h and hot isostatic pressed (HIP) at 1700 ℃ for 3 h show the best in-line transmittance of 47.6% at 700 nm and the highest redness of 52.0.

Key words: Ce-doped 8YSZ, red transparent ceramics, air pre-sintering, hot isostatic pressing, optical property
