| Abstract Scope |
Wettability between coke and pitch plays a decisive role in determining anode quality in aluminum smelting. Conventional techniques such as SyTAC, developed about 25 years ago within our company, have provided valuable insights but offer limited flexibility for evaluating a wide range of materials, particularly given the current lack of commercial support. In this study, an isothermal sessile drop method is developed to measure static contact angle at controlled, application-relevant temperatures across a variety of coke and pitch materials. Validation was performed through systematic comparison with the traditional method using multiple coke-pitch combinations, demonstrating strong correlation between the two approaches. Beyond validation, the proposed method offers significant advantages in flexibility and material screening capability. It enables rapid pre-assessment of raw material compatibility, facilitating the exploration of alternative feedstocks and supporting optimization prior to anode fabrication. This approach provides a practical framework for wettability characterization in both research and industrial applications. |
