Abstract
The characteristics (composition of the quenched samples, ingot, and evaporation products) are studied of the melt of the corium–high alumina cement system in a weight ratio of 1: 1. In the quenched samples of the melt and ingot, signs of phase separation in the molten state are found. Below a temperature of 2100°C above the melt, aerosol particles with trimodal size distribution are formed; however, above this temperature, the nature of the granulometry of aerosols is bimodal. Moreover, the formation rate of aerosols increases dramatically. The form of aerosol particles under all the experimental conditions was spherical.
