Aluminum Diboride Powder

Aluminum Diboride Powder Description

Aluminum boride Powder is an ionic compound, with a hexagonal crystal structure.  Aluminum boride at an absolute temperature slightly 40K (equivalent to -233 ℃) will be transformed into a superconductor. And its actual operating temperature is 20 ~ 30K. To reach this temperature, we can use liquid neon, liquid hydrogen, or closed-cycle refrigerator to finish cooling. Compared to the current industry using liquid helium to cool the niobium alloy (4K), these methods are simpler and more economical. Once it is doped with carbon or other impurities, magnesium diboride powder in a magnetic field, or there is a current passing, the ability to maintain the superconducting is as much as niobium alloys, or even better.

Ferrochrome Nitride Powder Description:

Ferrochrome Nitride Powder Application:

Ferrochrome, or ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy of chromium and iron, generally containing 50 to 70% chromium by weight.

Ferrochrome is produced by electric arc carbothermic reduction of chromite. Most of the global output is produced in and India, which have large domestic chromite resources. Increasing amounts are coming from Russia and China.

Production of steel, especially that of stainless steel with a chromium content of 10 to 20%, is the largest consumer and the main application of ferrochrome.

Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures. Chromium ore (an oxide of Cr and Fe) is reduced by coal and coke to form the iron-chromium alloy.

The heat for this reaction can come from several forms, but typically from the electric arc formed between the tips of electrodes at the bottom of the furnace and the furnace hearth.

This arc creates temperatures of about 2,800 °C (5,070 °F). In the process of smelting, huge amounts of electricity are consumed, making production very expensive in countries where power costs are high.

The tapping of the material from the furnace takes place intermittently. When enough smelted ferrochrome has accumulated in the furnace hearth.

The tap hole is drilled open and a stream of molten metal and slag rushes down a trough into a chill or ladle. Ferrochrome solidifies in large castings that are crushed for sale or further processed.

Ferrochrome is generally classified by the amount of carbon and chrome it contains.

The vast majority of FeCr produced is "charge chrome" from South Africa, with high carbon being the second largest segment followed by the smaller sectors of low carbon and intermediate carbon material.
