This article presents a brief review of the research progress achieved in the field of aluminium nitride (AlN) metastable cubic modifications synthesis. It covers mainly the synthetic approaches, such as carbothermal reduction nitridation (CRN), chemical vapour deposition (CVD), solvent thermal synthesis, high pressure phase transition and thin-fil...

A comparative study of the band structure and magnetic properties of the hexagonal and cubic modifications of aluminum nitride doped with boron, carbon, and oxygen in the nitrogen sublattice has been performed using the ab initio FLAPW-GGA method. Preliminary conclusions on the comparative chemical activity of these phases are drawn from estimates...

Background: High purity nanosized aluminum nitride synthesis is a current issue for both industry and science. However, there is no up-to-date review considering the major issues and the technical solutions for different methods. This review aims to investigate the advanced methods of aluminum nitride synthesis and its development tendencies. Also...

The phase stability, electronic structure, and magnetic properties of Al1–x Tix N compositions based on the metastable aluminum nitride modification with the rock-salt structure at low (x = 0.03) and high (x = 0.25) concentrations of titanium in the system have been investigated using the results of ab initio band calculations. It has been shown th...

Experimental results obtained in AlN synthesis by the high-temperature gas-phase method and analysis of reaction products phase composition are briefly described. It is demonstrated for the first time that dispersed aluminum nitride can be synthesized by this method from AlF3 in both hexagonal and cubic modifications.

Первопринципным методом FLAPW-GGA выполнено сравнительное исследование зонной структуры и магнитных свойств гексагональной и кубической модификаций нитрида алюминия, допированных бором, углеродом и кислородом по азотной подрешетке. На основании оценок энергий замещения атомов азота примесями были сделаны предварительные выводы о сравнительной химич...

Purity of AlN, synthesized by means of gas-phase technology, depends to a considerable extent on charge component and intermediate compound reactions with structural materials. Chemical aspects are considered for transformations and the nature of reaction of aluminium fluoride and nitride with different types of graphite , the effect of fluorides o...

Ultradispersed high-purity aluminum nitride powder was obtained at the Physico-Technological Institute on a unique experimental-industrial unit by a gas-phase method. The powder was obtained through the formation of aluminum monofluoride. However, there has been very little thermodynamic analysis of the interactions of the materials in the reaction...

Inorganic water-glass-based thermal pastes exhibit a higher thermal conductivity coefficient than silicon-based pastes. They can also be used at elevated temperatures. The optimum filler content, silicate modulus, application of a modifier and pressure were studied. As the result, a significant increase in the thermal conductivity at 508 °C could b...

Russian and overseas sources published in the last twenty years for aluminum nitride preparation methods are studied. Both basic and relatively simple technology, as well as atypical innovative procedures, are analyzed, making it possible to form a complete picture of aluminum nitride preparation methods within the world.
