The issue of developing compositions and technological parameters
compatible with traditional mayolica materials used in historical monuments, creating
ceramic products with high strength and aesthetic characteristics based on local raw
materials is considered. A ceramic mass was formed based on Kattabog clay soil,
Angren secondary- grey kaolin, aluminosilicate raw materials, and the technological
conditions of the firing process were analyzed. The composition of the samples was
analyzed using a dispersive X-ray fluorescence spectrometer (XRF), structural bonds
and functional groups were characterized using infrared (IR) spectroscopy.
Absorption peaks in the range of 909–786 cm⁻¹ in the spectrum indicate the presence
of tetrahedral coordination [AIO4] structural units of aluminum. This condition is
explained by the restructuring of the aluminosilicate lattice during the firing process,
the formation of high-temperature stable phases. The possibility of creating mayolica
ceramic materials with physico-mechanical, structural properties compatible with
historical architectural tiles based on local raw materials is scientifically
substantiated.
