About Iron Boride FeB Powder:
Iron boride (FeB) is a gray powder that is insoluble in water. FeB is harder than Fe2B, but more fragile and more likely to break on impact. Feb is a soft ferromagnetic compound that becomes paramagnetic at temperatures above 325°C (617°F).In the air, FeB powders begin to react with ambient oxygen above 300°C. Although a large number of FeB materials are expected to remain stable in air, FeB is a very hard compound (measured by Vickers indentation at 15-22 GPa), it is undesirable on bonded steel because the FeB layer is brittle and tends to flake off steel or iron.
Feb has a zigzag chain of boron atoms coordinated by seven iron atoms. The boron atom has a slightly twisted single-terminated triangular prism iron atom coordination and two boron atom neighbors. The B-B single bond distance is 178 PM, the Fe-B single bond distance is 215 — 220 PM, and the Fe-Fe single bond distance is 240 — 272 PM. Each triangular prism shares two rectangular faces with a nearby prism, thus forming an infinite sequence of the prism.
The FeB single crystal is occupied by the bond domain. The bond domain is parallel to the easy magnetization axis and perpendicular to the hard magnetization axis. The structure of a closed domain is described as “rows and twists of asterisks”.The bond domain has an obvious direction on the boundary of the main domain, while the closed domain is rhomboid.

How is Iron Boride FeB Powder produced?
The preparation method of iron boride FeB is as follows:
1. It is prepared by mixing boron with iron at a molar ratio of 1∶1 and cheating in argon at 1200 ~ 1300℃.
2. Reaction FeS and BCl3 in hydrogen at temperatures higher than 500℃, or from ferrous chloride solution and sodium borohydride (NaBH4).
Application of Iron Boride FeB Powder:
Fe-based coatings have recently gained attention for their mechanical, friction and corrosion resistance. Compared to the ceramic or cermet types used by humans before them, the iron-based material is relatively cheap, less strategic, and can be produced economically through a variety of thermal methods, and is easy to manufacture and machine.
Iron boride is commonly used to improve wear resistance, corrosion resistance, wear-resistance and oxidation resistance.
Iron boride is used in oil and gas refineries, chemical extraction, automotive, agricultural, stamping, textile extrusion and injection molding industries.
Storage Condition of Iron Boride FeB Powder:
The damp reunion will affect FeB powder dispersion performance and using effects, therefore, iron boride FeB powder should be sealed in vacuum packing and stored in cool and dry room, the iron boride FeB powder can not be exposure to air. In addition, the FeB powder should be avoided under stress.
Packing & Shipping of Iron Boride FeB Powder:
We have many different kinds of packing which depend on the iron boride FeB powder quantity.
Iron boride FeB powder packing:vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Iron boride FeB powder shipping: could be shipped out by sea, by air, by express, as soon as possible once payment receipt.
