Description of Aluminum diboride Powder
Aluminum diboride (AlB₂) powder is a compound formed between aluminum and boron, and borides like this are essential in both metal compounds and ceramic materials because of their distinctive properties. AlB₂ powder is usually produced through methods like high-temperature solid-state reactions or self-propagating high-temperature synthesis (SHS), which help achieve a stable phase and fine particle distribution.
This material stands out for its high hardness, excellent thermal and chemical stability, and good electrical conductivity. It’s commonly used in demanding applications, such as refractory linings in industrial furnaces, high-temperature protective coatings, and abrasives. Its high capacity to absorb neutrons also makes it valuable for nuclear reactors, where controlling neutron flow is critical.
Aluminum boride powder is well-suited for specific manufacturing processes, such as powder metallurgy and additive manufacturing. These properties make it a strong choice for creating durable, high-performance composites in industries like aerospace, automotive, and defense, where materials must withstand extreme conditions.

Nanodispersive aluminum boride prepared by a plasma recondensation of aluminum and boron micron powders
This work presents investigations into the composition and some properties of nanodispersive powders of aluminum boride prepared by the plasma-recondensation technique. It is shown that, under a strictly determined aluminum: boron ratio in the starting mixture and with the complete observance of technological processing parameters, aluminum boride (n-AB) nanopowders of the required composition and dispersivity can be obtained. SEM investigations of the aluminum boride samples reveal that aluminum boride powders are mixtures of spherical particles of different sizes and a significant agglomeration of the particles is observed. In general, the sizes of particles are varied from several dozens of nanometers up to 500 nm and more. Investigations into the thermal-oxidative activity of synthesized aluminum boride using thermogravimetric and differential thermal analysis show that these compounds are more active towards air than nanodispersive aluminum. The highest rate of oxidation of aluminum borides was observed in the temperature range of 680–700°C.
