The main objective of this work was to explore the improved water dispersibility obtained in natural graphite after its surface treatment. The superior flowability of the aqueous suspension of an alumina-rich representative castable matrix incorporating that surface-modified graphite without prior sonication has been observed. The typical role of alumina-based thin coating on graphite has also been addressed.

表面处理石墨改善含碳富铝可铸造基体的流变特性

这项工作的主要目的是探索天然石墨经过表面处理后获得的改善的水分散性。已经观察到，在没有事先超声处理的情况下，掺入了该表面改性石墨的富含氧化铝的代表性可浇铸基质的水性悬浮液具有优异的流动性。还解决了氧化铝基薄涂层在石墨上的典型作用。
