摘要:
玻璃通常通过高温熔体迅速冷却得到,熔体与容器的接触易导致非均匀成核发生,常导致玻璃形成能力较弱的组分产生析晶。悬浮法可提供超高熔制温度、超快冷却速度,可以用于制备高熔点以及玻璃形成能力较弱的体系。介绍了若干最常见的悬浮熔炼法,总结了此技术在几种功能玻璃体系(Al2O3 基、Nb2O5 基、TiO2 基和WO3 基)制备中的应用,并对该技术的发展做出了展望。该技术有助于研究人员对玻璃结构组成形成新的理解,为新型功能玻璃设计提供新思路。

?Glass is commonly fabricated by rapid cooling of high-temperature melt. However, heterogeneous nucleation easily occurs?at the interface between the melt and container, which could lead to devitrification for compositions with weak glass-forming ability.?Containerless processing (also called levitation) offers a super high melting temperature and enables super undercooling; it therefore?provide a solution for the fabrication of glasses with high melting point or low glass-forming ability. This article briefly reviews?several containerless methods and their applications in the fabrication of several novel functional glasses (including Al2O3-based,?Nb2O5-based, TiO2-based and WO3-based), and highlights future perspectives of these techniques. This technology may facilitate the?establishment of new understandings on glass structure and construction which will help the researchers to design novel functional?glass.
