Abstract
It is found that the time of establishing a critical contact angle of wetting the surface of a pressed sample made of polycrystalline quartz powder with different liquids is determined primarily by the viscosity of the liquid. It is shown that, in order to determine the critical contact angle of powder materials, it is necessary to record the moment at which the diameter of the base of a liquid droplet on the surface of a powder sample has a maximum value.
