Boric Acid (H₃BO₃)
General description
Boric acid (orthoboric acid, boron preparation) is a weak inorganic acid that has been used in industry for more than two centuries. Thanks to its antiseptic and functional properties, it is widely applied in glass and ceramics, construction materials, metallurgy, agriculture, and chemical manufacturing.
Boric acid is a colorless, flaky, odorless crystalline powder. It is soluble in water, glycerin, alcohol, salt solutions, and mineral acids. In nature, boric acid occurs as the mineral sassolite in some hot springs of volcanic origin, in mineral waters, and in natural brines.
A characteristic feature of boric acid is its ability to color a flame green. In the laboratory, boric acid was first obtained from borax by the chemist V. Homberg in 1702.

Production methods
Boric acid can be obtained by several industrial methods, for example:
- Reaction of sodium tetraborate decahydrate (Na₂B₄O₇·10H₂O, borax) with strong inorganic acids
- Dissolving boron hydrides (B₂H₆) or boron halides (e.g. BCl₃) in water
- Extraction from natural waters using ethanol or polyhydric alcohol mixtures (polyols)
- Recovery from natural brines using organic or mineral sorbents
- Processing of natural borate minerals
Applications
- Raw material for chemical synthesis and buffer systems
- Enamels and frits for ceramics and glass production
- Fiberglass, mineral wool, and other glass / ceramic materials
- Wood treatment compositions (disinfection and protection)
- Electrolytes for electroplating processes
- Photographic fixer and specialized photographic solutions
- Construction mixes and building materials
- Boron-containing fertilizers
- Formulations for pest and insect control
Safety, transport and storage
Boric acid is nonflammable and nonexplosive. By its effect on the human body, it belongs to hazard class 3 (moderately hazardous substances). Work with boric acid should be carried out using standard industrial protection:
- Rubber or nitrile gloves
- Respiratory protection in dusty environments
- Protective safety goggles
Boric acid can be transported by rail, sea, river, and road in covered vehicles protecting the product from moisture and contamination. Store in closed warehouses with natural ventilation, in original unopened packaging, away from food products and direct sunlight.
