Overview

abstract

• In this work, the contact angles of molybdenite powders in various size fractions (%2b150 μm,-150 %2b 75 μm,-53 %2b 38 μm,-38 %2b 20 μm, and-5 μm) were determined with the Washburn method by measuring the mass of capillary rise liquids in molybdenite powder beds as the function of time. It was shown that molybdenite powders had a smaller contact angle in superfine size range (-5 μm) than the common size range (%2b20 μm), which might be attributed to the large decrease of the face/edge ratio on molybdenite surfaces. Also, it has been found that the contact angle of molybdenite particles did not change as the decrease of particle size in the range of %2b20 μm. © 2014 Copyright Taylor and Francis Group, LLC.
