Ferrochrome Nitride Powder

Product Name: Ferrochrome Nitride Powder

Ferrochrome Nitride Powder Description:

Ferrochrome nitride is widely used in electric furnace and oxygen converter smelting nitrogen steel. Nitrogen is an element of austenite formation,

It is used as a component to add chromium manganese and chromium manganese nickel stainless steel to replace the shortage of nickel.

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.

Tungsten Carbide Powder

Product Name: Tungsten Carbide Powder

Brief Description of WC Tungsten Carbide Powder

Tungsten carbide powder (chemical formula: WC ) is a chemical compound (specifically, a carbide ) containing equal parts of tungsten and carbon atoms.

In its most basic form, tungsten carbide is a fine Gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments, and jewelry.

Physical Properties of WC Tungsten Carbide Powder

Tungsten carbide has a high melting point at 2,870 °C (5,200 °F), a boiling point of 6,000 °C (10,830 °F) when under a pressure equivalent to 1 standard atmosphere (100 kPa), the thermal conductivity of 110 W·m−1·K−1, and a coefficient of thermal expansion of 5.5 µm·m−1·K−1.

Tungsten carbide is extremely hard, ranking about 9 on Mohs scale, and with a Vickers number of around 2600.

It has Young’s modulus of approximately 530–700 GPa, a bulk modulus of 630–655 GPa, and a shear modulus of 274 GPa.

It has an ultimate tensile strength of 344 MPa, the ultimate compression strength of about 2.7 GPa and a Poisson’s ratio of 0.31.

Chemical Properties of WC Tungsten Carbide Powder

There are two well-characterized compounds of tungsten and carbon, WC and tungsten semi abide, W2C.

Both compounds may be present in coatings and the proportions can depend on the coating method.

At high temperatures, WC decomposes to tungsten and carbon and this can occur during high-temperature thermal spray, e.g., in high-velocity oxygen fuel (HVOF) and high energy plasma (HEP) methods.

Application of WC Tungsten Carbide Powder 

1 Used for Producing high capability nano-crystalline or superfine horniness alloy, hard-face abrasion-resistant spraying and petrochemical cracking catalyst;

2. Used for chipless forming tools; Cutting tools; Mining tolls; Nano-composites (for enhanced hardness, strength, and wear resistance);
3. Used for erosion-resistant coatings; wear-resistance coatings; Corrosion-resistant coatings; Wear-resistant parts
4. To produce hard carbide.

Zirconium Carbide Powder

Product Name: Zirconium Carbide Powder

Zirconium Carbide Powder Description:

Like most carbides of refractory metals, zirconium carbide is sub-stoichiometric, i.e., it contains carbon vacancies.

At carbon contents higher than approximately ZrC0.98 the material contains free carbon.

ZrC reacts with water and acids and is pyrophoric.

It becomes readily oxidized in the air when exposed to elevated temperatures.

It shows a high amount of corrosion resistance property and contains carbon vacancies.

It reacts with water as well as acids.

Application:

1.Used as an abrasive, in metal cladding, in cermet, incandescent filaments, and cutting tools.

2. The mixture of zirconium carbide and tantalum carbide is an important cermet material.

3. Hafnium-free zirconium carbide and niobium carbide can be used as refractory coatings in nuclear reactors.

4. Zirconium carbide is used extensively as a coating of uranium dioxide and thorium dioxide particles of nuclear fuel.

5. The coating is usually deposited by thermal chemical vapor deposition in a fluidized bed reactor.

6.  High-temperature wear-resistant surface materials
