Monitoring of the Interaction of Aluminum Alloy and Sodium Chloride as the Basis for Ecological Production of Expanded Aluminum

The article deals with the monitoring of the behavior of sodium chloride in interaction with the aluminum alloy melt. Sodium chloride is an excellent substance for the production of expanded aluminum materials. Its melting point is 801°C and an advantageous is that NaCl can be easy applicable from an ecological point of view. The theoretical calculations of melt penetration between sodium chloride grains were performed and the angle of wetting...
