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.

Product Name: Iron Boride Powder

Iron Boride Powder Description

Iron Boride Powder is often used to improve abrasion resistance, corrosion resistance, wear resistance, and oxidation resistance. It is used in oil and gas refinery, chemical extraction, automotive agricultural, stamping, textile extrusion, and injection molding industries. Iron-based coatings recently gained attention for their mechanical, frictional, and corrosion-resistant properties. As compared to the ceramic or cermet type of materials people have used before, iron-based materials are relatively inexpensive, less strategic, and can be produced economically by various thermal methods with ease of fabrication and machining.

Niobium Boride Powder

Product Name: Niobium Boride Powder

Niobium Boride Powder

Niobium boride Powders having NbB, NbB2, and Nb3B4 phases in various amounts and single-phase NbB powders were successfully synthesized by using powder metallurgy methods from related metal oxide raw materials in the presence of a strong reducing agent. Nb2O5, B2O3, and Mg powder blends were milled at room temperature by a high-energy ball mill for a different time. Subsequently, an undesired MgO phase was removed from the milled powders by HCl leaching to constitute NbB–NbB2–Nb3B4 as final products, and they were subjected to an annealing process at 1500 °C for 4 h to observe probable boride transformation. Characterization was carried out by XRD, DSC, PSA, SEM/EDX, TEM, and VSM.

The effects of milling time (up to 9 h) on the formation, microstructure, and thermal behavior of the final products were investigated. The reduction reaction took place after milling stoichiometric powder blends for 2 h. Nano-sized NbB–NbB2–Nb3B4 powders in high purity were obtained in the absence of any secondary phase and any impurity via mechanochemistry by milling for 5 h and leaching with 4 mol/L HCl. After annealing, pure and nano-sized NbB–NbB2–Nb3B4 powders transformed to a single NbB phase without leaving behind NbB2 and Nb3B4 phases.
