摘 要: 理解高温熔体(熔盐、液态金属及合金)在碳材料表面的润湿行为对发展高温能源储存与转换、材料铸造与加工、电解冶金、熔盐制备碳等技术十分关键，而目前对这一主题的系统评述还很罕见。本文首先结合实际应用，对常见典型碳材料/高温熔体固-液界面润湿性特点进行了梳理，评述比较了目前常用的三种高温接触角测定方法，随后重点对两类润湿机理进行了讨论：固-液界面非反应的物理润湿和发生化学/电化学反应的反应润湿，以期深化和拓展对于高温熔体在碳表面润湿性的认识，为相关应用提供有关界面润湿的指导。

Abstract:Well understanding of wetting behavior on carbon material surface by molten melts (molten melts, liquid metal or alloy) plays a critical role in developing high-temperature energy storage and transfer technique, material casting and processing, metal production by electrolysis in molten salts and carbon materials production by molten salts carbonization and activation. However, thus far, the systematic reviews focus on this subject are scarce. In this paper, typical wetting characteristics of carbon/molten melts solid-liquid surface were clarified and three currently used contact-angle-measuring methods were reviewed based on practical industrial applications. And then the wetting mechanisms of solid-liquid interface were emphatically discussed in the way of two kinds: non-reactive wetting and reactive wetting (chemical reactions or electrochemical reactions). We hope this review can broaden our understanding of nature of the wettability of carbon material surface by high-temperature melts and guide us to solve the practical industrial questions.
