Technological and Quality Aspects of the Use of Innovative Inorganic Binders in the Production of Castings

The production of cores for the pre-casting of holes in castings places high demands on the quality of the molding mixtures used. For this reason, organic binders are still used to a large extent, which, although they meet the technological requirements, are a source of pollutant emissions during th...
