Iron boride 
Chemical formula: FEB 
Molecular weight: 66.66 
Melting point: 1652 ℃ 
Density: 7.15g/ML (25/4 ℃) 
CAS number: 12006-84-7 
Production method: 
Mix boron and iron in a molar ratio of 1:1 and prepare by co heating in argon at 1200-1300 ℃. 
2. React FeS and BCl3 in hydrogen at temperatures above 500 ℃, or prepare them by reacting ferrous chloride solution with sodium borohydride (NaBH4). 
Material structure: 
The arrangement of iron boride is in a zigzag chain shape, with iron atoms at the corners of a triangular prism and boron atoms at the center of the triangular prism, covalently connected in the zigzag chain. 
Physical and chemical properties: 
The melting point of iron boride is 1652 ℃, with a density of 7.15g/mL. It is soluble in dilute and concentrated nitric acid, concentrated and 1:1 hydrochloric acid solutions, 1:1 H2SO4 and HClO4, with a concentration of 1.1 μ B. At low temperatures, it exists in the form of α -, while at high temperatures, it exists in the form of β - with the same Tc (602K). With the change of magnetic moment, it transforms from α to β type. Both can form ferromagnetic materials. Reacts with boiling water. Hard texture, difficult to melt, and good corrosion resistance. 
Boron iron has ceramic properties such as high hardness, as well as metallic properties such as thermal and electrical conductivity. The boride coating on the surface of iron has excellent mechanical properties, friction properties, and anti-corrosion properties. Iron boron (FeB) is a gray powder that is insoluble in water. FeB is harder than Fe2B, but more brittle and more prone to fracture during impact. 
Purpose: 
1. Target material; 
2. Boron iron is a strong deoxidizer and boron addition agent in steelmaking production. The greatest function of boron in steel is to significantly improve hardenability and replace a large amount of alloying elements with only a very small amount. In addition, it can also improve mechanical properties, cold deformation properties, welding properties, and high-temperature properties.   
A preparation of ultrafine iron boride: 
Mix ferrous gluconate solution with boric acid solution, and then spray dry to obtain spray drying material. The molar ratio of ferrous gluconate solution to boric acid is 1:1.01 1.02; The spray drying material is sintered in methane atmosphere, the sintering time is 510h, the sintering temperature is 800 1200 ℃, and the reaction is conducted to obtain the returned material; Continue to introduce carbon dioxide into the raw material and react at a temperature of 700 850 ℃ for 24 hours to obtain sintered material; The sintered material is subjected to airflow crushing, screening, and vacuum packaging to obtain ultrafine iron boride. This method can prepare ultrafine boron iron with small particle size and large BET, and high purity.
