摘    要：为了探讨工业应用TiB₂阴极材料的途径,本文采用由中温炭还原法制得的TiB₂原料,在配入一定量的石墨成分后,将其热压成TiB₂(C)片,用高温可见光座滴法和X射线座滴法分别研究了1000℃时,铝电解质及电解质熔盐覆盖下的铝液对此种含炭TiB₂热压片润湿性,测得了非极化条件下有熔盐存在时,铝在纯TiB₂热压片上的润湿角近乎零度,铝在TiB₂(C)上的润湿角为10°左右,并讨论了铝对TiB₂(C)试样片的润湿机理。

Abstract: Hot-pressed TiB₂-graphite tablets with varying amounts of graphite were prepared in order to seek the way of applying TiB₂ cathodic materials.The wettability of TiB₂(C)by aluminium and cryolite-alumina was studied by the sessile drop method.The wetting angle of pure TiB₂ and TiB₂(C)by aluminium in cryolite-alumina melts was measured.The wetting mechanism was also discussed.
