Heat of Immersion of Various Si₃N₄ Powders

Abstract

The heat of immersion of various Si₃N₄'s were measured using different liquides. The electrostatic field strengths of solid surfaces were estimated from the relationship betweeen the heat of immersion and the dipole moment of the liquid.
Results of the heat of immersion isotherm show that the surface of Si₃N₄ had a heterogeneously active site for the -OH radical in the form of butanol. In addition, the mechanism of the interaction during immersion was discussed.
