摘要
高发射率陶瓷材料是当前最热门的功能材料之一。将它应用于工业炉中不仅能够使炉内热量分布均匀还能提高加热速度,从而提高工业炉的加热效率并达到低碳节能的目的。高发射率陶瓷材料优势突出,包括红外发射率较高、化学性质稳定且热稳定性佳等。本文从红外辐射机理出发,综述了近年来应用较多的几种高发射率陶瓷材料体系的研究进展。主要介绍了掺杂改性高发射率陶瓷材料的思路与工艺,进一步阐述了高发射率陶瓷材料应用于工业领域的研究现状,并对此类材料目前的缺陷与未来的发展方向作出了建议与展望。
High-emissivity ceramic materials have received more and more attention because of their high performances.A higher heating efficiency and subsequent energy saving effect can be achieved when they are adopted in the industry furnaces.These materials not only improve the heating rate,but also endow an even heat distribution in the furnace.The advantages of these materials include the high infrared emissivity,stable chemical properties and prominent thermal stability.Based on the mechanism of infrared radiation,the research progress in several high-emissivity ceramic materials are reviewed in this paper.Moreover,the preparation of doped high-emissivity ceramic materials and latest research status are introduced,and the future development trend is also discussed.
