Cobalt Boride CoB Powder CAS 12619-68-0

Cobalt boride is a compound with many properties and uses. It is usually composed of cobalt and boron; cobalt diboride (CoB2) and cobalt triboride (CoB3) are common forms. 

Cobalt diboride is a white or bluish powder with high density, hardness, melting point, and thermal conductivity.Cobalt diboride is insoluble in water and acid at room temperature but can react with boron, carbon, oxidants, and so on at high temperatures. It is mainly used to synthesize and modify high-temperature superconducting materials, ceramics, glasses, catalysts, and other fields. 

Cobalt triboride is a black powder with a tetragonal crystal system, and its crystal structure is Pearson symbol oP6-dcm. It has high hardness, melting point, and good thermal and chemical stability, so it has many application prospects in high temperatures, high frequency, high humidity, and other harsh environments. Cobalt triboride is mainly used in high-temperature superconducting materials, electronic packaging materials, advanced ceramics, and other fields. 

In addition, cobalt boride also has good magnetic and semiconductor properties, so it is also widely used in magnetic materials, electronic devices, sensors, and other fields. At the same time, cobalt boride is also used in aerospace materials, high-grade refractory materials, wear-resistant materials, and other fields.

Mechanical mixing method: Metal cobalt and boron powder are mixed in a ball mill or mortar, and the two powders are fully contacted and mixed evenly through ball milling or grinding. The bulk or granular cobalt boride is made by pressing or sintering. 

Chemical vapor deposition (CVD): The elements or compounds of cobalt and boron are heated to high temperatures and react with a reactive agent such as hydrogen or ammonia in the gas phase to produce a thin film of cobalt borides. The cobalt boride film obtained by this method has the advantages of high purity, high density, and high flatness. It is suitable for preparing high-performance electronic devices and superconducting materials. 

Molten salt electrolysis method: the oxide or salt of cobalt and boron is melted at high temperature, the current is passed into the molten mixture, and the cobalt boride is gradually precipitated on the cathode. This method is suitable for large-scale production, but the obtained cobalt boride is low purity and requires post-treatment. 

Hydrothermal method: the compound of cobalt and boron is dissolved in water, and then the reaction is carried out in a sealed high-temperature and high-pressure reactor to prepare cobalt boride. The cobalt boride obtained by this method has high crystallinity, high purity, and high activity and is suitable for preparing high-performance catalysts and superconducting materials. 

Ion exchange method: a solution containing cobalt ions is mixed with a solution containing boron ions, and an ion exchange reaction produces cobalt boride. This method is suitable for preparing high-purity cobalt boride but requires ion exchange and washing operations, and the process is long.
