摘要
超高温氧化物晶体,比如钇稳定氧化锆、氧化镁、氧化铀以及部分稀土氧化物等,熔点往往高达2 300℃以上。它们在激光、超导、核燃料等领域具有重要应用,但在生长方法、坩埚材料、温度监测、温场控制等方面面临多重挑战。本文总结了目前少数几种超高温氧化物晶体生长研究进展,分析了各种生长技术的优缺点,探讨了超高温氧化物晶体生长的前景。
Ultra-high temperature oxide crystals, such as MgO, ZrO2, UO2 and Lu2O3, have important applications in laser, superconductor and nuclear rod. However, they have ultrahigh melting points above 2 300℃ and the great challenges in crystal growth include growth technique, crucible, temperature measurement and temperature profile. The recent progress on these crystals was reviewed and the growth techniques were introduced. The technical innovation was discussed for successful growth of super high temperature oxide crystals.
