摘 要: 理解高溫熔體(熔鹽、液態(tài)金屬及合金)在碳材料表面的潤濕行為對發(fā)展高溫能源儲存與轉(zhuǎn)換、材料鑄造與加工、電解冶金、熔鹽制備碳等技術(shù)十分關(guān)鍵，而目前對這一主題的系統(tǒng)評述還很罕見。本文首先結(jié)合實際應用，對常見典型碳材料/高溫熔體固-液界面潤濕性特點進行了梳理，評述比較了目前常用的三種高溫接觸角測定方法，隨后重點對兩類潤濕機理進行了討論：固-液界面非反應的物理潤濕和發(fā)生化學/電化學反應的反應潤濕，以期深化和拓展對于高溫熔體在碳表面潤濕性的認識，為相關(guān)應用提供有關(guān)界面潤濕的指導。

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.
