Preparation and properties of rare earth doped Y2O3 transparent ceramic

随着激光器技术的迅猛发展，激光晶体与玻璃的应用限制逐渐暴露出来，例如:晶体生产周期长，成本高，掺杂浓度不高，玻璃热学性能较差等。而透明陶瓷因具有光学均匀性好、机械性能好、热导率高、掺杂浓度高、制备周期短，生产成本低等优点，其制备与应用技术蓬勃发展。 本论文选择物化性能优良的Y2O3作为研究对象，通过粉体制备方法的比较与选择，烧结助剂的筛选，制备工艺的制定和优化，最终获得气孔率低、微观结构均匀、光学性能优良的透明陶瓷。并在此基础上制备了稀土离子掺杂的Y2O3With the development of high power solid lasers, the application restriction of traditional laser materials (crystal and glass) has been exposed, such as long production cycle, high cost, low doping concentration of crystal and low thermal properties of glass. So the transparent ceramic has developed for its numerous advantages: excellent optical uniformity, good mechanical properties, outstanding thermal properties, high doping concentration, short period cycle, low cost and so on. This paper focused on Y2O3 transparent ceramic, which has excellent physical and chemical properties. Through the comparison of different powder preparation methods, the selection of sintering additive, the design and optimizing of fabrication process, Y2O3 transparent ceramics with high optical transmittance and unifor
