Trends in the use of bentonite clays
Litiyo i Metallurgiya (FOUNDRY PRODUCTION AND METALLURGY), 2020 The paper gives a general description of the areas of application of bentonite clays. A number of deposits were evaluated in terms of their use in various technological processes. Analysis of directions of application of bentonite clays in foundry was carried out.Using the methods of X-ray and gas chromatographic analysis, scanning electron microscopy,
