Global AlN powder market trend 2023-2027 What are Aluminum Nitride Characteristics? by Newsvegasreportnewswire

U.S. natural gas futures rose about 5 percent to a near nine-week high as global energy prices surged on concerns over a pricing plan for energy exports, keeping U.S. LNG export demand near record highs. U.S. natural gas prices have risen despite forecasts of mild weather and lower-than-expected demand, which will allow utilities to fill up storage facilities next week. On Wednesday, Germany launched an emergency plan to manage gas supplies in Europe's largest economy. If natural gas supplies are interrupted or stopped, the German government could take unprecedented steps to limit electricity supply.
Affected by the increase in the price of natural gas, the price of the AlN powder will also increase.

Aluminum Nitride Research History
Aluminum nitride is a kind of ceramic material with excellent comprehensive performance, and its research can be traced back more than 100 years ago. It was discovered by F. Birgeler and A. Gutter in 1862, and synthesized by J.W. Mallets for the first time in 1877, but there was no practical application in the following 100 years. It was used as fertilizer only as a nitrogen-fixing agent.
 
Aluminum nitride is a covalent compound with a low self-diffusion coefficient and high melting point, which makes it difficult to sinter. It was not until the 1950s that the first aluminum nitride ceramics were successfully made and used as refractory materials in the smelting of pure iron, aluminum, and aluminum alloys. Since the 1970s, with the deepening of research, the preparation technology of aluminum nitride has become increasingly mature, and its application scope has also been expanding. Especially since the 21st century, with the rapid development of microelectronics technology, electronic machine, and electronic components is toward miniaturization, light-duty, integration, as well as the development direction, such as high reliability and high power output, more and more complex heat dissipation device to the substrate and packaging material put forward higher request, to further promote the vigorous development of the industry of aluminum nitride. 
 

Aluminum Nitride Characteristics
Structure
Aluminum nitride (AlN) is a hexagon wurtzite covalent bond compound with lattice parameters A =3.114, C =4.986. Pure aluminum nitride is blue-white, usually gray or off-white, and is a typical iii-wide bandgap semiconductor material. 



Performance
Aluminum nitride (AlN) has the characteristics of high strength, high volume resistivity, high insulation and pressure resistance, thermal expansion coefficient, and a good match with silicon, not only used as a sintering agent or strengthening phase of structural ceramics, especially in the field of ceramic electronic substrate and packaging materials in recent years, its performance is far superior to alumina. 
 

Aluminum Nitride Thermal Conductivity Mechanism
Of the series of important properties of aluminum nitride, the most remarkable is its high thermal conductivity. A great deal of research has been done on the thermal conductivity mechanism of aluminum nitride, and a relatively perfect theoretical system has been formed. The main mechanism is heat transfer through lattice or lattice vibration, that is, by lattice wave or thermal wave. The results of quantum mechanics tell us that lattice waves can be treated as the motion of a particle, the phonon. Thermal waves also have wave-particle duality. Thermal phonons transfer heat through mutual restriction and coordination of vibrations among structural elements (atoms, ions, or molecules). If the crystal is a non-elastic body with a perfect structure, the heat can be transferred freely from the hot end of the crystal to the cold end without any interference and scattering, and the thermal conductivity can reach a very high value. The thermal conductivity is mainly controlled by crystal defects and phonon scattering.
 
The theoretical thermal conductivity of AlN can reach 320W·m-1·K-1, but the actual thermal conductivity of AlN is less than 200W·m-1· k-1 due to impurities and defects in AlN. This is mainly because the structural elements in the crystal cannot have a completely strict uniform distribution, and there are always different sparse and dense regions, so the current-carrying phonons will always be interfered with and scattered in the propagation process.

In a recent interview with Izvestia, Russian Federation Council Chairman Matviyenko said that Russia is open to dialogue with the West based on mutual respect, but the opportunity to resume dialogue will only come after the end of special military operations.  

Matviyenko also noted that Europe currently lacks politicians who can make independent decisions.  She said the EU's strategy to wean itself off Russian energy by 2027 would be costly, with Russia supplying 40 percent of Europe's gas, 27 percent of its oil, and 46 percent of its coal, and was essentially "anti-European" and a "tax" on US global dominance.

On Sweden's and Finland's plans to join NATO, Matviyenko said Russia will take corresponding measures if NATO weapons and equipment appear in the two countries, and Russia is capable of guaranteeing its own security. 

Besides, speaking by video at an international conference, Ukraine's minister of agricultural policy and Food, said the country's grain AlN powder are expected to continue to be influenced by international situations.
