Increasing the service life and reducing the cost of refractories remains an actual task for metallurgical production. One of the ways to solve it is the use of new composite materials in the production of modern refractories. The paper presents the test results of the alloying of ladle products PUPK-SH by composite boron-containing antioxidants, obtained by the SHS method. As a result of laboratory tests, it was established that PU-products contained SHS-antioxidants NITRO-BORAL NB-1 (BN·Al2O3) and BorTiX® MM (2TiB2·TiC) grades, instead or together with current antioxidant additive (aluminum powder APV-P grade), has the better characteristics of slag resistance, oxidation and physical and mechanical properties after firing. Based on the results of laboratory tests the products PUPK-SH grade, containing boron-containing SHS-antioxidants, were recommended for pilot industrial testing.

The paper presents data on the influence of zirconium dioxide micropowder addition, partially stabilized by yttrium, on high-temperature resistance performance of fired periclase products, as well as on some physical and physical –mechanical properties. Microscopic examination of the structure of highpurity synthetic periclase and zirconium dioxide micropowder was carried out. The possible mechanism of interaction of the introduced additive with impurities contained in periclase was determined. Substantial influence of zirconium dioxide micropowder on high-temperature properties of refractory was established.

The strategy of sustainable development assumes proper management of man-made waste, capable of ensuring their reuse and reducing the associated environmental burden on the environment. A promising direction for the utilization of water treatment sediments is the possibility of their use in a mixture with peat as a potential raw material for the production of construction and ceramic materials. An installation has been developed for the selection of milling peat, its mixing with water treatment sediments, drying of the resulting mixture and grinding for subsequent use in the production of construction and ceramic materials.

The influence of additives of different nature on grinding, compressibility and sintering of calcined magnesite was investigated. It was found that the investigated recycled additives, when introduced in the amount of up to 0,5 wt. %, do not significantly change the grain composition of calcined periclase after grinding, do not effect the compressibility of powders, do not change their chemical and phase composition after firing up to the temperature of 1870 оC. An additive based on dust-like waste of titanium production enables increasing the density of the obtained briquette by 1,0‒3,5 % or reducing the briquette firing temperature by 50‒100 °С.

Ceramic materials based on cordierite Mg2Al4Si5О18, their different compositions and methods of preparation are considered. The results of tests of thermal shock resistance of ceramic samples of different compositions are presented. The thermal shock resistance of the obtained samples is more than 15 heat changes (1000 °C ‒ 15 °C running water). This cordierite material, in the production of which it is supposed to use only native raw materials, has good prospects when used as a thermo stable catalyst carrier for controlling industrial emissions, as well as car exhaust gases.
