Preparation of composite materials using borate ore of the inder deposit RK in the mode of solid -phase combustion
The article presents experimental results on the production of composites based on the ZrSiO<sub>4</sub>-MgB<sub>2</sub>O<sub>3</sub> and ZrSiO<sub>4</sub>-Al-B<sub>2</sub>O<sub>3</sub> system using borate ore from the Inderskoye field of RK with a wide variation of the concentration ratios of the components in the original mixtures using self-propagating high-temperature synthesis (CBC), which is a type of combustion. It is shown that the products of exothermic interaction in the combustion process are high-temperature compounds of zirconium boride and aluminum and magnesium oxides, which in the ceramic composite form a dispersed phase and a ceramic bond. The influence of the composition of the charge of the initial charge, preliminary mechanical activation before the conduction of SV-synthesis on the formation of the microstructure, morphology and strength characteristics of the synthesized composite materials, is established. The possibility of using borates of the Inder field of the Republic of Kazakhstan as a boron-containing component in the preparation of composite materials by the method of self-propagating high-temperature synthesis is shown.
