European Commission President Ursula von der Leyen recently called on India and other countries to support sanctions against Russia over the Ukraine incident. At The Raisina Dialogue forum, von der Leyen said, "We earnestly appeal to all members of the international community to support our efforts to achieve lasting peace."
Von der Leyen says countries around the world that have been suffering from the virus for two years must now deal with higher food, energy, and fertilizer prices. What is happening in Ukraine will not only determine the future of Europe, but also have profound implications for the rest of the world.
Because of the Russia-Ukraine conflict, the prices of many other commodities like the AlN powder are expected to continue to rise in the future.
Aluminum Nitride Applications
Due to the piezoelectric properties of aluminum nitride, epitaxially grown thin films of crystalline Aluminum nitride are used for surface acoustic sensors (SAW) deposited on silicon wafers. One application is an RF filter, widely used in mobile phones, called a 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 an ultrasound and can be used for aerial ranging at distances up to one meter.
Metallization allows AlN to be used in electronic applications similar to alumina and beryllium oxide. AlN nanotubes, as inorganic quasi-one-dimensional nanotubes, with isoelectronic carbon nanotubes, have been proposed as chemical sensors for toxic gases.
Currently, there is a lot of research into the development of light-emitting diodes (LEDs) that operate under ULTRAVIOLET light using gallium nitride-based semiconductors. Using aluminum gallium nitride alloys, wavelengths as short as 250 nm have been achieved. In 2006, inefficient AlN LED emission at 210 nm was reported.
AlN application industries include:
Dielectric layer in an optical storage medium,
The electronic substrate, chip carrier that needs a high thermal conductivity,
As a crucible for growing gallium arsenide crystals,
Steel and semiconductor manufacturing.
Aluminum Nitride Difficulties
At present, aluminum nitride also has some problems.
First, the powder is easy to form aluminum hydroxide with a hydroxy group in the wet environment, and the alumina layer is formed on the surface of AlN powder. The alumina lattice is dissolved into a large amount of oxygen, which reduces its thermal conductivity but also changes its physical and chemical properties, bringing difficulties to the application of AlN powder. The inhibition of hydrolysis treatment of AlN powder is mainly to coat the surface of AlN particles with a substance using a chemical bond or physical adsorption to isolate them from water, to avoid the occurrence of a hydrolysis reaction. At present, the main methods of inhibiting hydrolysis treatment are surface chemical modification and surface physical coating.
Second, the high price of aluminum nitride limits its application to a certain extent. The preparation of aluminum nitride powder generally requires a high temperature, which leads to high energy consumption in the process of production and preparation, and at the same time, there are safety risks, which is also the main drawback that some high-temperature preparation methods cannot achieve industrial production. Moreover, the impurities in the process of production preparation added to the production of harmful products or problems, such as excessive carbon reduction reaction carbide powder removal problems, as well as the chemical vapor deposition method of by-product hydrogen chloride removal problems, which require the preparation of aluminum nitride for reaction products in the process of the purification, it also led to the preparation of aluminum nitride production cost is high.
Aluminum Nitride Price
The price is influenced by many factors including the supply and demand in the market, industry trends, economic activity, market sentiment, and unexpected events.

Recently, the first press conference of the Boao Forum For Asia Annual Conference 2022 was held. Two flagship reports were released at the conference: "Asia's Economic Prospects and Integration Process 2022" and "Sustainable Asia and the World 2022-Green Transformation in Action in Asia".
The flagship report points out that the global economy will recover in 2021, and the pace of economic integration in the Asia-Pacific has not stopped even in the face of the impact of COVID-19. The Asia-Pacific region has provided new impetus for the world's economic recovery and institutional building.
The report gives an outlook on the Asian economy, noting that a number of factors will affect Asian economic growth. For example, mutated strains such as Delta and Omicron have become more transmissible, and many economies are experiencing epidemic peaks again. The Ukraine crisis has triggered geopolitical changes in Asia and Europe, leading to higher commodity prices, which may affect the global energy supply and energy transformation.
The report pointed out that the Asian economy will still be in the process of recovery in 2022, but the growth rate may moderate. According to the report, Asia's economic growth in 2022 is likely to be lower than the current IMF forecast, which is projected at 4.8%.
Affected by several factors, the supply of the AlN powder is erratic and thus its prices are expected to go higher in the future.
