Corrosion-related irreparable metal failures can cause massive losses in various sectors, including agricultural engineering and construction. Steel structures are typically coated to withstand corrosion pressures during the service life specified in technical standards to avoid corrosion damage. This article presents research results on metallurgical cast iron slags and a mixture of slags with electro-filter dust to form silicate anticorrosive coatings. X-ray phase analysis, electron, and optical microscopy were used to analyze the surface nucleation of crystals in glasses using cast iron slags, a combination of steelmaking slag, and electro-filter dust with the addition of Cr2O3. It is shown that the main phases crystallizing from the surface of the samples are diopside (CaO∙MgO∙2SiO2). When 1.5 - 2.0 wt.% Cr2O3 was added, the results showed that diopside phase glasses could be made with a cast iron slag level of up to 72 wt.%. Studies have shown the important role of Fe2+, and Mg2+, especially in samples containing cast iron slag, based on the most fusible compounds obtained. The optimal model of glass formation and crystallization was established as a result of the analysis of these compositions, and the microhardness of slag glass-crystalline materials was investigated. It was found that the hardness of the obtained glass-crystal materials increases in the presence of chromium oxide. The research revealed the possibility of synthesizing glass-crystal materials from cast-iron slags and dust of electro-filters
