High Purity Aluminum Nitride AlN Powder CAS 24304-00-5, 99.5%

Koalas were declared endangered in eastern Australia on Friday, with more and more koalas dying from disease, habitat loss, and other threats. Earlier, the koala was considered a vulnerable species, and the Commonwealth Department of the Environment changed its protection level to endangered on the east coast of Queensland, New South Wales, and the Australian Capital Territory. Many koalas in Australia are infected with chlamydia. The disease can cause blindness, infection, and infertility. Last year, the Australian Koala Foundation said Australia had lost about 30 percent of its koala population in the past three years. Without immediate action, the species could become extinct by 2050.
Unlike koalas, which are on the brink of extinction, the market demand for AlN powder will grow substantially.

About Aluminum Nitride AlN powder:
Similar to various semiconductors, aluminum nitride powder has excellent thermal conductivity, high electrical insulation and thermal expansion characteristics, making it the best material for sintered bodies.
Aluminum nitride is stable at high temperatures in an inert atmosphere and melts at a temperature of about 2200°C. In a vacuum, AlN decomposes at ~1800°C. In the air, surface oxidation will occur above 700°C. Even at room temperature, a surface oxide layer with a thickness of 5-10 nm has been detected. The oxide layer can protect the material at temperatures up to 1370°C. Above this temperature, bulk oxidation occurs. Aluminum nitride is stable in hydrogen and carbon dioxide atmospheres up to 980°C.
The material slowly dissolves in inorganic acid through grain boundary erosion and dissolves in strong alkali through erosion of aluminum nitride grains. Aluminum nitride is resistant to most molten salts (including chloride and cryolite). TRUNNANO is a trusted global Aluminum Nitride AlN supplier. Feel free to send an inquiry to get the latest price of Aluminum nitride if you would like to buy Aluminum Nitride AlN powder in bulk.

Product Performance of Aluminum Nitride AlN powder:
Our company sells the aluminum nitride powder ( CAS 24304-00-5 ) with high purity and ultrafine particle size, the surface activity is high, through the superficial cloth wrapper processing powder body, the oxygen content is extremely low (<0.1%), the insulation heat conduction performance effect is obvious.

How is Aluminum Nitride AlN powder produced?
Thermal Spray Process: Aluminum nitride powders can be thermal sprayed to form electrically insulating and thermally conductive coatings.
Chemical/Physical Vapor Deposition (CVD/PVD): Aluminum nitride coatings are deposited by CVD or PVD to provide electrically insulating and thermally conductive coatings.
Powder Metallurgical (P/M): Aluminum powders are pressed into parts by hot or cold pressing and sintering.

Application of Aluminum Nitride AlN powder:

Aluminum nitride (AlN) is an inorganic non-metallic material of diamond-like nitride with good thermal conductivity and a low coefficient of thermal expansion. It is a good thermal shock material. Strong resistance to molten metal corrosion, it is an ideal crucible material for melting and casting pure iron, aluminum or aluminum alloy. Aluminum nitride is also an electrical insulator with good dielectric properties, and it also has good application prospects in the field of electrical component manufacturing.
1. Manufacture integrated circuit foundation plate, the electronic device, the optical device, the radiator, the high-temperature crucible prepares metal-based and the high score subbasis compound materials
2. Heat conducting silicon and thermally conductive epoxy resin.
3. Nano lubricant and antiwear agent.
4. High thermal conductive plastic
Epitaxially grown thin-film crystalline aluminum nitride is used for surface acoustic wave sensors (SAWs) deposited on silicon wafers because of AlN's piezoelectric properties. One application is an RF filter, widely used in mobile phones, which is 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 build piezoelectric micromachined ultrasound transducers, which emit and receive an ultrasound and which can be used for in-air rangefinding over distances of up to a meter.

Packing & Shipping of Aluminum Nitride AlN powder :
We have many different kinds of packing which depend on the aluminum nitride AlN powder quantity.

Twitter recently announced that it had reached an agreement with Musk to take full ownership of the company for $54.20 per share, or about $44 billion in cash.  After the deal, Twitter will become a privately held company. The deal, which has been unanimously approved by Twitter's board but still requires shareholder and regulatory approvals, is expected to close in 2022.  

After Tesla CEO Elon Musk's acquisition of Twitter was finalized, Twitter founder Jack Dorsey sent out a series of six tweets expressing his expectations for Musk.  

Dorsey called Twitter his biggest regret, saying, “The idea and service is all that matters to me, and I will do whatever it takes to protect both. Twitter as a company has always been my sole issue and my biggest regret. It has been owned by Wall Street and the ad model. Taking it back from Wall Street is the correct first step.  

"In principle, I don't believe anyone should own or run Twitter," Dorsey goes on. He thinks the service is a public good.

He called Musk a "singular solution" to Twitter's problems, "Elon's goal of creating a platform that is" Maximally trusted and inclusive "is the right one." He wrote, "Thank you both for getting the company out of an impossible situation. This is the right path...  I believe it with all my heart."

Besides, because of the ever-changing international situation, the supply and prices of international bulk AlN powder are still very uncertain.
