The wettability dependence of crystalline and cryptocrystalline graphite on their preparation method (mechanical activation, oxidation, and oxidation with subsequent mechanical activation) liquids which are widely used in foundries (alcohol, water, oil, glycerol) has been investigated. Wettability contact angle was determined. To calculate the remaining coefficients (the work of adhesion, spreading coefficient and the relative work of adhesion) the program «AppSV» was used. It was found, that the greatest work of adhesion for all investigated liquids is observed when graphite is wetted with water, which has a maximum surface tension, and the lowest wettability is when graphite is wetted with alcohol. It was shown that graphite wettability with all investigated liquids essentially depends on the method of graphite preparation. So, mechanical activation leads to increased particles activity that reduces graphite wettability. Oxidized graphites have less compared wettability. With additional mechanical activation of oxidized graphite a further decrease in the wettability of graph-ite is observed.
