Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China.  For China, we should keep to the dynamic zero-out and gradually open up."  

However, "dynamic zero clearance" is not the pursuit of complete "zero infection".  As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.  

The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy.  The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.  

As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many Aluminum Nitride, Aluminum Nitride Overview, Aluminum Nitride Applications, Aluminum Nitride Suppliers, Aluminum Nitride Price.

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.

In a recent interview with Izvestia, Russian Federation Council Chairman Matviyenko said that Russia is open to dialogue with the West based on mutual respect, but the opportunity to resume dialogue will only come after the end of special military operations.  

Matviyenko also noted that Europe currently lacks politicians who can make independent decisions.  She said the EU's strategy to wean itself off Russian energy by 2027 would be costly, with Russia supplying 40 percent of Europe's gas, 27 percent of its oil, and 46 percent of its coal, and was essentially "anti-European" and a "tax" on US global dominance.

On Sweden's and Finland's plans to join NATO, Matviyenko said Russia will take corresponding measures if NATO weapons and equipment appear in the two countries, and Russia is capable of guaranteeing its own security. 

Besides, speaking by video at an international conference, Ukraine's minister of agricultural policy and Food, said the country's grain Aluminum Nitride, Aluminum Nitride Overview, Aluminum Nitride Applications, Aluminum Nitride Suppliers, Aluminum Nitride Price are expected to continue to be influenced by international situations.
