Global Aluminum nitride (AlN) market trend 2024-2029 Spherical aluminum nitride and its preparation method and application process by Newsnapoleonuk

Russia's insistence on paying for Russian gas in rubles has rattled European countries: Greece held an emergency meeting of suppliers, the Dutch government would urge consumers to use less gas, and the French energy regulator told consumers not to panic. Russian gas meets one-third of Europe's annual energy needs.

Russia said they could expand their demand for ruble payments for other commodities, including oil, grain, fertilizer, coal, and metals, which raised the risk of recession in Europe and the US. 

Moscow is expected to unveil its ruble payment plan in early April, but it said it would not immediately ask buyers to pay for gas in rubles.  

Western countries have said paying in rubles would be a breach of contract, and renegotiation could take months or longer. This uncertainty has pushed commodity market prices higher.

The supply and prices of other commodities like the Aluminum nitride (AlN) could also be affected.

Overview of spherical aluminum nitride AlN powder

Aluminum nitride (AlN) is a solid nitride of aluminum. It has a high thermal conductivity of 321w/(m · K) and is an electrical insulator. Its wurtzite phase (w-aln) has a band gap of about 6 EV at room temperature, which has potential applications in optoelectronics working at deep UV frequency.

Aluminum nitride AlN powder is stable at high temperatures in an inert atmosphere and melts at about 2200 °C. In vacuum, AlN decomposes at about 1800°C. In air, surface oxidation occurs above 700 ℃, and a 5-10 nm thick surface oxide layer is detected even at room temperature. This oxide layer protects the material at temperatures up to 1370 °C. Above this temperature, a large amount of oxidation will occur. It is stable at 980°C in hydrogen and carbon dioxide atmosphere. The material is slowly dissolved in inorganic acid through grain boundary erosion and in strong alkali through erosion of aluminum nitride grains. The material is slowly hydrolyzed in water. Aluminum nitride is resistant to most molten salts, including chloride and cryolite. Aluminum nitride can be patterned using reactive ion etching based on Cl2.

Aluminum nitride is an inorganic powder of high thermal conductivity material. Because of its excellent comprehensive properties such as high thermal conductivity, good insulation, low dielectric constant and expansion coefficient equivalent to Si material, it has attracted more and more attention. It is widely used in large-scale integrated circuits, high thermal conductivity substrates in electronic field, inorganic thermal conductivity fillers, high-performance structural ceramics and other fields.

With the advent of 5g era, all kinds of electronic devices are becoming more and more integrated, and the power is increasing. Higher requirements are put forward for its heat dissipation performance. For various packaging resins used in the electronic field, the best way for thermal conductive materials to improve their heat dissipation performance is to add inorganic insulating fillers with high thermal conductivity, and aluminum nitride is one of the best choices. Increasing the filling amount requires the powder to be dense spherical and the particle size range from tens of microns to hundreds of microns, so as to ensure the combination of large and small particles and achieve the purpose of high filling and good fluidity.

At present, the known preparation methods of spherical aluminum nitride powder are mainly carbothermal reduction method, direct nitriding method and in-situ nitriding method, but there are some defects in varying degrees, such as poor particle size distribution, insufficient sphericity, low density, loose and porous, which hinder its application in heat conducting materials.

Thermal spraying process: aluminum nitride powder can be thermally sprayed to form electrical insulation and thermal conductive coating. Chemical / physical vapor deposition (CVD/PVD): aluminum nitride coating is deposited by CVD or PVD to provide electrical insulation and thermal conductivity coating.  

Powder metallurgy (P/M): aluminum powder is pressed into parts by hot pressing or cold pressing and sintering.

Application of spherical aluminum nitride AlN powder

Aluminum nitride is a kind of inorganic powder with high thermal conductivity. Because of its high thermal conductivity, good insulation, low dielectric constant, and silicon material has considerable expansion coefficient and excellent comprehensive properties, it has attracted more and more attention. It is widely used in the fields of large-scale integrated circuits, electronic substrates, high thermal conductivity, thermal conductivity inorganic fillers, high-performance structural ceramics and so on.

With the advent of 5g era, the integration of various electronic devices is higher and higher, and the functions are more and more powerful. In order to improve the heat dissipation performance of various packaging resins used in the electronic field, the best way is to add inorganic insulating fillers with high thermal conductivity to the materials. Aluminum nitride is one of the best choices. In order to increase the filling amount, the powder is required to be dense and spherical, and the particle size ranges from tens of microns to hundreds of microns, so as to ensure that the particle size and particle size of the composite can achieve high filling and good fluidity

Due to the piezoelectric properties of AlN, epitaxially grown thin film crystalline aluminum nitride is used for surface acoustic wave sensor (SAW) deposited on silicon wafer. One application is RF filter, which is widely used in mobile phones. It is called thin film bulk acoustic resonator (FBAR). This is a MEMS device that uses aluminum nitride sandwiched between two metal layers. AlN is also used to construct piezoelectric micromechanical ultrasonic transducers that emit and receive ultrasound and can be used for aerial ranging over a distance of up to one meter. The metallization method allows AlN to be used in electronic applications similar to alumina and beryllium oxide. As inorganic quasi one-dimensional nanotubes, AlN nanotubes and carbon nanotubes have been proposed to be used as chemical sensors for toxic gases. At present, a lot of research has been carried out on the development of light-emitting diodes working under ultraviolet light using gallium nitride based semiconductors. Using aluminum gallium nitride alloy, the wavelength as short as 250 nm has been realized. In 2006, low efficiency aln# led emission at 210 nm was reported.
