Global Aluminum Niitride market trend 2024-2028 The Applications of Aluminum Niitride by Newspfcstal

Diamonds are forever, Gold is precious but which is rarer? Gold is a heavy metal formed during the collision of neutron stars and is one of the rarest elements on Earth.During the formation of the earth, heavy elements gradually accumulated towards the core under the influence of the earth's gravitational force. This means that the closer you get to the Earth's crust, the harder it is to find large quantities of gold.The average concentration of gold in Earth's crust is "very, very low" at just 4 parts per billion. Gold concentrations need to be 1,250 times that level to form a market-worthy deposit.
Diamond is a common element - the product formed by carbon under extremely high pressure, and it is a dense carbon element. Carbon also has a looser element called graphite, which is what makes pencil lead. Compared to gold, the average concentration of carbon in the Earth's crust is about 200,000 parts per billion.
In terms of elements, gold is far rarer than diamonds. Due to the predictable and volatile nature of gold, the Aluminum Niitride is undoubtedly a good investment opportunity.

What is Aluminum Nitride?
Aluminum nitride, covalent bond compound, chemical formula is AIN, is an atomic crystal, belongs to diamond-like nitride, hexagonal system, wurtzite crystal structure, non-toxic, white or off-white.
The main features of Aluminum Nitride
AlN is stable up to 2200°C. The strength at room temperature is high, and the strength decreases slowly with the increase of temperature. Good thermal conductivity, small thermal expansion coefficient, is a good thermal shock material. It has strong corrosion resistance to molten metal, and is an ideal crucible material for casting pure iron, aluminum or aluminum alloy. Aluminum nitride is also an electrical insulator with good dielectric properties and is also promising as an electrical component. The aluminum nitride coating on the gallium arsenide surface protects it from ion implantation during annealing. Aluminum nitride is also a catalyst for the conversion of hexagonal boron nitride to cubic boron nitride. It reacts slowly with water at room temperature. It can be synthesized by aluminum powder in ammonia or nitrogen atmosphere at 800~1000℃, and the product is white to gray-blue powder. Or by the reaction of Al2O3-C-N2 system at 1600~1750℃, the product is off-white powder. Or prepared by vapor-phase reaction of aluminum chloride and ammonia. The coating can be synthesized by the vapor-phase deposition method of AlCl3-NH3 system.

The use of Aluminum Niitride
It is reported that most of the research today is developing a semiconductor (gallium nitride or alloy aluminum gallium nitride) based light emitting diode that operates in ultraviolet light with a wavelength of 250 nanometers. In May 2006, it was reported that an inefficient diode can emit light with a wavelength of 210 nm [1]. A single aluminum nitride crystal has an energy gap of 6.2 eV measured by the reflectance of vacuum ultraviolet rays. In theory, the energy gap allows some waves with wavelengths around 200 nanometers to pass through. But in commercial implementation, there are many difficulties to overcome. Aluminum nitride is used in optoelectronic engineering, including as dielectric layers in optical storage interfaces and electronic substrates, as chip carriers with high thermal conductivity, and for military applications.
Due to the properties of the piezoelectric effect of aluminum nitride, epitaxial stretching of aluminum nitride crystals is also used for surface acoustic wave detectors. The detectors are placed on silicon wafers. There are very few places where these thin films can be produced reliably.
Aluminum nitride ceramics have the characteristics of high room temperature and high temperature strength, small expansion coefficient and good thermal conductivity, and can be used as heat exchanger materials for high temperature structural parts.
Using aluminum nitride ceramics to resist the corrosion properties of iron, aluminum and other metals and alloys, it can be used as crucible and casting mold materials for smelting Al, Cu, Ag, Pb and other metals.

With Tesla's new factory in Germany starting production, Volkswagen is just weeks away from finalizing plans for its 2 billion euro ($2.2 billion) electric car factory, which it hopes will bring it closer to its U.S. competitor. Tesla says it takes just 10 hours to produce a Model Y at its new factory in Grunheide, near the German capital, while Volkswagen takes three times as long to produce its ID.3 electric car. Volkswagen's productivity has been increasing by around 5 percent a year, said Christian Vollmer, head of the production at the Volkswagen brand.
The improvement in the efficiency of production vehicles will bring opportunities for Aluminum Niitride. In the future, the demand for Aluminum Niitride will become more and more extensive. Please feel free to contact us for the latest news on Aluminum Niitride.
