Chemical Properties
-Thermal Decomposition: When heated above 90°C, it decomposes to release ammonia gas. At high temperatures, it converts to boron trioxide (B₂O₃) with traces of ammonia.
-Reactivity: As a basic salt, it neutralizes acids with heat generation, but less vigorously than strong bases
-Decomposition Reaction: The tetrahydrate loses crystalline water and ammonia upon heating, eventually forming boron oxide
Safety: Non-flammable; however, toxic nitrogen oxides may form during combustion
Main Applications and Uses
-Boron Compound Intermediate: Primary precursor for synthesizing various boron chemicals and specialized boron compounds
-Telecommunications Equipment: Key component in electrolyte solutions for electrolytic capacitors, enhancing performance and reliability
-Fire Retardant: Used as a flame retardant for wood, textiles, paper, and other materials; inhibits combustion by forming a protective glassy layer
-Glass Manufacturing: Produces high-grade, specialty glasses with improved thermal and chemical resistance
-Wood Preservation: Acts as a preservative and fireproofing agent for wood products, protecting against fungal decay and pests
-Metal Protection: Functions as a corrosion inhibitor in metal processing and protective coatings
-Detergents and Cleaners: Component in industrial and household detergents, enhancing cleaning performance
-Welding and Brazing: Used as a flux component in welding, brazing, and soldering operations
-Advanced Materials: Precursor for synthesizing boron-nitrogen co-doped porous carbon materials for supercapacitors
-Analytical Reagent: Laboratory reagent for chemical analysis and synthesis
