Boric acid (H₃BO₃) is a White crystalline powder with a slippery feel , it is an inorganic weak acid , soluble in water, and widely used in the glass industry (to improve heat resistance and transparency), medicine (disinfection, treatment of fungal infections, and external eye wash), agriculture (trace elements), nuclear energy (controlling nuclear fission), and pest control . 

• Chemical formula : H₃BO₃

• Appearance : White powder or transparent crystals

• Feel : Smooth

• Solubility : Slightly soluble in cold water, but solubility increases with increasing temperature; soluble in alcohol, glycerol, etc.

• Acidity : The aqueous solution is weakly acidic and can form stronger acidic complexes with polyols. 

Main uses

• industry :

• Glass : Improves heat resistance, transparency, and mechanical strength.

• Nuclear power : It absorbs neutrons and controls the rate of nuclear fission.

• Flame retardant .

• To manufacture other boron compounds .

• Medical :

• Disinfection and antibacterial (e.g., athlete's foot, candidiasis).

• It can be used as an eye wash after dilution.

• Agriculture : Essential micronutrients for plants, promoting growth.

• Pest control : Kill ants, cockroaches, and termites.

• Cosmetics : Found in skin care products such as talcum powder.

• Food : It was once used as a preservative, but its use is restricted in many countries due to toxicity issues.
