Abstract
The destruction of ice by means of chemical substances is based on the property of some substances to form mixtures with ice that have a lower melting temperature than their components. This is called the eutectic temperature, and the concentration of the eutectic solution is dependent on the properties of the chemical substance. Ice melts in an eutectic solution up to the maximal concentration of the brine corresponding to the given temperature. The character and degree of ice destruction depend on the substance, size of particles, spraying norms, temperature and structure of the ice. Ice melts in a uniform layer from the top downwards under the effect of powdered chemical substances. Individual lumps of chemical substances penetrate into the ice, forming twisting canals with strong partitions. The ice strength is reduced because of violation of its solidity.
