Applications:
Crystalline boron powder’s unique combination of hardness, thermal stability, and electrical resistivity makes it suitable for diverse high-performance applications:
Aerospace and Defense: Utilized in lightweight high-strength composites and structural components due to its high hardness and heat resistance.
Advanced Ceramics: Integral in the production of high-performance ceramic materials with excellent wear resistance and thermal stability.
Nuclear Industry: Acts as a neutron absorber in control rods and shielding materials due to boron’s high neutron capture cross-section.
Fuel and Propellant Systems: Serves as an ignition aid and high-energy fuel component in pyrotechnics, rocket propellants, and combustion systems.
Corrosion Inhibition: Boron compounds derived from boron powder are used in antifreeze formulations, brake fluids, and hydraulic systems to prevent rust and degradation of ferrous materials.
Abrasives: The extreme hardness (Mohs 9.3) makes boron ideal for high-speed cutting, lapping, and polishing applications.
Photoelectric and Electrochemical Applications: Used in tanning, photography, fuel cells, and electrolytic processes due to its unique electron behavior.
Biocidal and Pest Control: Boron-based compounds act as effective physical biocides, disrupting pest cell structures without toxic chemicals.
