What is Aluminum Boride? The influence of certain factors on the kinetics of the process of obtaining aluminum borides (burning rate, ingot formation, and phase separation) was investigated. In this study, we report the registration of diboride using the SHS protocol. The synthesis of aluminum diboride from boric anhydride occurred by the aluminothermic method. The initial components were boron trioxide and aluminum in the form of powders. Researchers paid special attention to the degree of grinding of the charge-fluxing substances. The influence this had on the rate of development of the degree of charge concentration was studied. A composition was chosen to calculate the degree of charge according to the speed obtained from several experiments. The melting was carried out with the following charge densities in g/cm3: 0.80, 1.08, 1.18, 1.74. The method of melting was ignition from above. The experimental results allowed us to conclude that the nature of the change in the combustion rate of the system, where there was an excess of the reducing agent in the charge, is the same.
Kinetics of the Synthesis of Aluminum Boride by the Self-Propagating High-Temperature Synthesis Method An increase in the combustion rate, where there was an excess of aluminum of up to 20%, was likely because the reaction area of the charge components increased. In addition, an increase in speed can be explained by a decrease in heat losses due to a reduction in the melting time. With an increase in excess aluminum above 20% of the stoichiometry, the observed decrease in the combustion rate can be explained by a decrease in the specific heat of the process due to the melting of the excess aluminum, which played the role of a ballast An important trend in the improvement of one of the most resource-intensive modern industries, metallurgy, is the reduction of the consumption of resources, both material and energy. Along with traditional types of energy (such as electrical), the production of ferroalloys and rare metals uses the chemical energy of reduction of metal oxides by reducing metals with a high affinity for oxygen, such as aluminum, silicon, boron, etc., as well as their alloys. The undoubted advantage of the latter is the unlimited reserves in nature and their environmental safety.
Aluminum borides are a promising energy compound for high-energy systems for various purposes Developing new equipment and technology is largely associated with creating new materials capable of operating at high speeds and temperatures. To meet these requirements, materials must have complex physicochemical and mechanical properties. Recently, many studies have been directed toward creating oxygen-free refractory compounds based on aluminum borides, characterized by high refractory properties and high energy characteristics. Aluminum borides are a promising energy compound for high-energy systems for various purposes. Aluminum borides are introduced into steels and some alloys of non-ferrous metals (aluminum, copper, nickel, etc.) to make them more fine-grained and significantly improve their mechanical properties. The addition of boron to high-speed steel significantly improves its cutting properties. This is explained by the fact that metal borides formed at high temperatures have high hardness and wear resistance.
