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 AlN powder is undoubtedly a good investment opportunity.
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.

According to Reuters, U.S. Treasury officials said they would discuss with G7 leaders pricing caps and tariffs on Russian oil as an alternative to the embargo, which would keep the market supplied, limit price spikes, and reduce Russian revenues.
The EU foreign ministers' meeting was held in Brussels. The meeting failed to agree on the sixth round of sanctions, including an oil embargo on Russia, because of objections from Hungary.
EU High Representative for Foreign Affairs and Security Policy said at a press conference after the meeting, that the meeting failed to reach an agreement on the final adoption of the sixth round of sanctions, the permanent representatives of member states to the EU will continue to discuss. The foreign ministers faced similar difficulties trying to reach an agreement on an oil ban. He said Hungary's position was based on economic rather than political concerns.
Hungary is highly dependent on Russia for energy, getting more than 60 percent of its oil and 85 percent of its natural gas from Russia.
A few days ago, the European Commission submitted the sixth round of proposed sanctions against Russia, including a total ban on Russian oil imports by the end of this year. Hungary immediately objected and said it wanted substantial compensation from the EU to offset its loss from giving up Russian oil.
The AlN powder price is predicted to increase in the next few days, due to geopolitical factors.
