Název v původním jazyce

Wettability of thermally treated Calcium pyrophosphate and Kaolinite: effect of annealing temperature

Popis výsledku v původním jazyce

In the present study the influence of treatment conditions (annealing temperature) of calcium pyrophosphate (CPP) and kaolinite on wetting behavior in selected liquids was evaluated. Latter materials have significant technological importance in several applications mainly as a filler matrices. Studied CPP was obtained from Prayon, Inc., Augusta Georgia, USA and kaolinite was obtained from Imerys SPS China clay powders. In the case of kaolinite powders, with increasing heating temperature contact angleswere decreased, for ethylene glycol and ethanol. Minor decrease was obtained also for water and acetone. In the case of calcium pyrophosphate the similar trends were obtained, except acetone, reflecting in both cases changes of the wettability in direction to more wetting surfaces. In the paper more detail evaluation will be presented, where the effects of surface chemistry and roughness will be stressed.
