Аннотация: The contact angles of molten NaCl and CaCl2 on hydroxyapatite (HAp) in air at 866 and 880°C are close to zero. Wettability and the kinetics of spreading in the NaCl/HAp system were not affected by the reaction product presaturation of a melt or by substrate density and roughness; the rate of spreading for NaCl/HAp was described by the De Genes model of viscous dissipation, while it slowed down significantly in case of CaCl2/HAp due to the interfacial reaction resulting in a surface tension gradient.
