        Iron boride is a compound composed of two elements, iron and boron, belonging to the 

metal boron group. Iron boride is a material with important application value, and has wide 

applications in industrial manufacturing, electronics, optics, aerospace and other fields.
        The preparation methods of iron borate mainly include chemical vapor deposition, rapid 

solidification, arc melting, halide molten salt electrolysis, etc. Among them, chemical vapor 

deposition is one of the most commonly used preparation methods. The specific operation is to 

deposit the two gases of iron and boron on the substrate in an appropriate proportion through 

vapor deposition at high temperature, thereby forming a solid FeB film. The rapid solidification 

method is to rapidly solidify the two elements of iron and boron at high temperature, thereby 

preparing iron borate block materials.
        Iron boride has many excellent physical and chemical properties. It has good hardness, wear 

resistance, and conductivity, as well as excellent corrosion resistance and high-temperature resistance. 

Iron boride is generally a gray black crystal with a metallic luster and a density of 7.21g/cm ³. It is 

unstable in air and easy to oxidize. At high temperatures, iron boride can form alloys with chromium 

and other elements, so it is often used as an additive for other metal alloys.
        Iron borate has a wide range of applications. Firstly, it is widely used in the manufacturing of 

tools and cutting tools. Secondly, it is also used as a semiconductor material in electronic devices, 

such as boost diodes, solar cells, thermocouples, etc. It is also used in optoelectronic products such 

as optical lenses, sunglasses, and car lights. In addition, iron borate is also widely used in the aerospace 

field and plays an important role in the construction of spacecraft.
        In general, ferroboron is a material with important application value. Its preparation method is 

simple, performance is excellent, and application range is wide, making ferroboron have a wide range 

of application prospects in industrial manufacturing, electronic technology, optical technology, 

aerospace technology, and other fields. In the future, with the continuous development of new material 

technology, the application of ferroboron will continue to expand and deepen, making greater 

contributions to the continuous development and progress of human society.
