As the world deals with potential supply shortages, oil prices are soaring again, with more dramatic spikes and sudden drops expected.

For consumers, that means more expensive gas for longer - prices at the pump remain above $4 a gallon. For the economy, that means more inflation. In addition to the pressure on consumers, any business that relies on oil -- from airlines and truck drivers to chemical companies and plastics producers -- will face higher costs.

Mr Pickering estimates that 2m to 3m barrels a day of Russian oil shipped by water are frozen out of the market with no direct buyers. Due to the soaring oil price, the price of the Aluminum Nitride powder in the chemical industry will also be greatly affected. He said China and India are continuing to buy Russian crude. "I'm sure there will be others willing to take on more over time," he said. Mr Pickering said he did not expect oil to return to $130 a barrel, but added that it could happen. Francisco Branch, head of commodities and derivatives at Bank of America, said the US market was ready for cyclical price spikes and price swings in the Aluminum Nitride powder.

Introduction to Aluminum Nitride AlN Powder
Aluminum nitride is a covalent bond compound. The chemical formula is AIN. It is an atomic crystal, belongs to the diamond-like nitride, hexagonal crystal system, has a wurtzite type crystal structure, non-toxic, white or off-white.
Aluminum nitride is a synthetic mineral that does not occur naturally in nature. The crystal structure of AlN is hexagonal wurtzite type, with low density (3.26g/cm3), high strength, good heat resistance (Decomposition happens at about 3060℃), high thermal conductivity, corrosion resistance, and other advantages. 
 
Physicochemical Properties of Aluminum Nitride AlN Powder
AlN remains stable at a maximum temperature of 2200℃. Its strength at room temperature is high, and the strength decreases slowly with the increase in temperature. AlN has good thermal conductivity, and a low thermal expansion coefficient, so it is a good heat shock material. 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. It is also a promising electrical component. The aluminum nitride coating on gallium arsenide protects it from ion implantation during annealing. Aluminum nitride is also a catalyst for conversion from hexagonal boron nitride to cubic boron nitride. 
It reacts slowly with water at room temperature. It can be synthesized from aluminum powder in ammonia or nitrogen at 800~1000℃. The product is white to grayish-blue powder. Or by al2O3-C-N2 system reaction synthesis at 1600~1750℃, the product is gray powder. Or aluminum chloride and ammonia gas should be opposite. The coating can be synthesized from the AlCl3-NH3 system by vapor deposition.
 
In summary,
1. Has high thermal conductivity (about 320W/m·K), which is close to BeO and SiC, and is more than 5 times that of Al2O3;
2. Excellent electrical properties (eg, dielectric constant, dielectric loss, body resistivity, dielectric strength); 
3. Good mechanical properties. The flexural strength is higher than that of Al2O3 and BeO ceramics, and can be atmospherically sintered; 
4. Good optical transmission characteristics; 
5. Non-toxic.

Applications of Aluminum Nitride AlN Powder
Because of the piezoelectric properties of AlN, the extensional extension of al nitride crystals is also used in surface acoustic wave detectors, which will be placed on silicon wafers.
Aluminum nitride ceramics have high room temperature and high-temperature strength, a small coefficient of expansion, and good thermal conductivity, so they can be used as high-temperature structural parts of the heat exchange equipment materials.
Aluminum nitride ceramics can be used as crucibles and casting mold material for melting Al, Cu, Ag, Pb, and other metals by virtue of their corrosion resistance to iron, aluminum, and other metals and alloys.
Aluminum nitride ceramics is a new kind of high technology ceramics. Aluminum nitride substrate has the characteristics of high thermal conductivity, non-toxic, corrosion resistance, high-temperature resistance, good thermochemical stability, and so on. It is an ideal packaging material, heat dissipation material, circuit components, and interconnect carriers for large-scale integrated circuits, semiconductor module circuits, and high-power devices. It is also the best additive to improve the thermal conductivity and mechanical properties of polymer materials, so aluminum nitride ceramic can also be used for smelting non-ferrous metal and semiconductor gallium arsenide crucible, thermocouple protection tubes, high-temperature insulation parts, microwave dielectric ceramic materials, high temperature resistant, corrosion-resistant structure and microwave transparent aluminum nitride ceramic products, used as a high thermal conductive ceramic production materials and resin, filler, etc. Aluminum nitride is an electrical insulator with good dielectric properties. The aluminum nitride coating on gallium arsenide protects it from ion implantation during annealing.
