Properties and Applications of Aluminum Nitride

As the European Union tries to reduce its dependence on Russian energy, the Russian president recently said Russia would try to shift its energy exports to the east, adding that there was no way for European countries to give up Russian gas immediately.

Russia supplies about 40 percent of the EU's gas, and western sanctions imposed over the conflict with Ukraine have complicated financing and logistical arrangements for existing agreements, hitting Russian energy exports, the report noted.  

Russia has been building closer ties with China and other Asian countries as the European Union debates whether to impose sanctions on Russian gas and oil and member states seek supplies from elsewhere, Reuters said.  

"So-called partners from unfriendly countries admit that they cannot survive without Russian energy, including gas," the Russian president said in a televised government meeting. There is no reasonable alternative to Russian gas in Europe right now."  

He also said Europe was driving up energy prices and destabilizing markets by talking about cutting off Russia's energy supplies. Russia, which produces about a tenth of the world's oil and a fifth of its natural gas, will need new infrastructure to increase energy supplies to Asia, he said.

He ordered Moscow to submit a plan by June 1, including "the expansion of transport infrastructure to countries in Africa, Latin America, and the Asia-Pacific region".  

He also sought to clarify the possibility of integrating two pipelines -- the Sakhalin-Khabarovsk-Vladivostok gas pipeline in the Far East and the "Power of Siberia" gas pipeline to China -- into Russia's unified gas supply system. In theory, connecting these routes to larger gas networks could allow Russia to divert gas from Europe to Asia.

Because of the ever-changing international situation, the supply and prices of international bulk Aluminum Nitride, Aluminum Nitride Overview, Aluminum Nitride Applications, Aluminum Nitride Suppliers, Aluminum Nitride Price are still very uncertain.

Aluminum Nitride Overview

Aluminum nitride is stable at high temperatures in an inert atmosphere, melting at temperatures around 2200°C. In a vacuum, AlN decomposes at about 1800°C. In air, surface oxidation occurs above 700°C. Surface oxide layers as thick as 5-10 nm can be detected even at room temperature. The oxide layer protects the material at temperatures up to 1370°C. Above this temperature, extensive oxidation will occur. Aluminum nitride is stable up to 980°C in hydrogen and carbon dioxide atmospheres.

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 the gas phase reaction of aluminum chloride and ammonia. The coating can be synthesized by the vapor deposition method of the AlCl3-NH3 system.

Application of Aluminum Nitride

Aluminum Nitride (AlN) is a diamond-like nitride inorganic non-metallic material with good thermal conductivity and low thermal expansion coefficient. It is a good thermal shock material. It has strong corrosion resistance to molten metal, and is an ideal crucible material for smelting and casting pure iron, aluminum or aluminum alloy. Aluminum nitride is also an electrical insulator, has good dielectric properties, and has good application prospects in the field of electronic component manufacturing.

1. Manufacture of integrated circuit substrates, electronic devices, optical devices, heat sinks, high-temperature crucibles, and preparation of metal-based and high-resolution composite materials

2. Thermally conductive silicon and thermally conductive epoxy resin.

3. Nano-lubricants and anti-wear agents.

4. High thermal conductivity plastic

Due to the piezoelectric properties of AlN, epitaxially grown thin-film crystalline aluminum nitride is used for surface acoustic wave sensors (SAW) deposited on silicon wafers. One application is RF filters, which are widely used in cell phones and are known as thin-film bulk acoustic resonators (FBARs). This is a MEMS device that uses aluminum nitride sandwiched between two metal layers.

Aluminum nitride is also used to construct piezoelectric micromachined ultrasonic transducers, which transmit and receive ultrasonic waves and can be used for aerial ranging up to one meter.
