Global AlN powder market trend 2024-2030 What are Aluminum Nitride Characteristics? by Newsiberocruceros

After Russia pledged to scale back its military operations around Kyiv and in northern Ukraine, the prices of most industrial metals fell, led by aluminum, showing people's concerns for supply shortage eased.

At an earlier time, the West imposed sweeping sanctions on Russia for its invasion of Ukraine, which aroused concerns about the supply problem because Russia is a major producer of nickel, aluminum, and copper. 

Russia is also a major gas supplier to Europe, where potential supply disruptions are seen as hitting power-intensive aluminum and zinc AlN powder are still very uncertain.

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.

Southern Copper Corp (SCCO.N) recently said its Peruvian mine remained closed after a six-week standoff with protesters and blamed the Peruvian government for failing to intervene in the safety of its 1,300 workers and their families.  

The company said in a statement that a recent agreement to end protests at the Cuajone mine required the company to withdraw complaints against protest leaders because railways transporting minerals and supplies remained blocked. Production has been suspended since the end of February.  

Peru's Energy Ministry said in a separate statement that it had also reached an agreement with Southern Copper to start talks to find common ground with local communities.  

"If we shut down for a year, the government will stop receiving more than 3.1 billion soles ($830 million) in taxes and royalties, and 8,000 direct and indirect jobs will be lost. This is what we want to avoid, "Southern Copper added in the statement.

Peru has faced a wave of protests from indigenous communities, who accuse mining companies of not providing enough jobs and funding to poor local residents.  

Central bank officials said last week that protests against copper mines such as MMG's Las Bambas and Southern Copper's Cuajone were dragging down the economy.  

Peru is the world's second-largest copper producer and mining is an important source of tax revenue for the country. It is estimated that the supply and prices of the AlN powder will be influenced by that.
