Boron powder (CAS: 7440-42-8) is a multifunctional industrial raw material, with its core applications mainly concentrated in metallurgy, chemical engineering, new materials and scientific research fields.
1. Metallurgical industry: Key additives
As a deoxidizer and degassing agent, boron powder is used in the smelting of non-ferrous metals such as copper, aluminum and magnesium to remove impurities like oxygen and nitrogen from the metal melt, thereby enhancing the purity and mechanical properties of the metals.
As an alloying element, it is added to steel or other metals to improve the hardness, wear resistance and high-temperature resistance of the materials.
2. Chemical engineering field: Important reaction raw materials
Boron powder is used to prepare borides (such as sodium borohydride and boron nitride), which are widely applied in organic synthesis, catalysts, flame retardants and other scenarios.
As the basic raw materials for preparing boric acid and borates, such products are indispensable in glass manufacturing, detergents and agricultural fertilizers.
3. New Materials and Energy field: High-performance components
High-purity boron powder can be used to manufacture semiconductor materials or as a neutron absorber in nuclear reactors.
In the field of new energy, amorphous boron powder can be used as a dopant for the cathode material of lithium batteries to enhance the cycle stability and capacity of the batteries. It can also be used to prepare high-performance ceramics or composite materials.
4. Other special purposes
In the military field, boron powder can be used as a component of rocket propellants to improve combustion efficiency.
In the field of scientific research, boron powder is used to synthesize new boron-based compounds or as an experimental reagent in materials science research.
