Abroad, they are actively engaged in “cold” sintering of materials, including ceramic, which is a mechanically and thermally conditioned mass transfer process that allows for low-temperature integration of various materials. The paper presents the results of research on low-temperature sintering and optimization of firing regimes for ceramic materials by introducing a salt complex with a liquidus temperature of 825оC into a charge based on natural and man-made rocks of the Republic of Tyva. The optimal concentrations of salt-containing additives in the ceramic mass, which affect the roasting properties of the resulting materials, have been determined. It was found that the introduction of a complex of salts into the ceramic charge promotes earlier sintering of the shard and the production of high-quality wall ceramics at lower temperatures, which leads to a reduction in energy costs during firing of products.
