Using the theory of heterogeneous formation of gas bubbles in a melt on the surface of non-wettable particles with a cavity, the influence of the linear energy of the contact boundary of three phases on the nucleation rate is considered. An estimate of the change in the contact angle depending on the line tension between the melt, gas and particle was obtained. It has been determined that with a negative energy value the contact angle increases. It is shown that the energy of line tension reduces the energy of the appearance of nuclei of critical sizes and increases the rate of nucleation.
