Boric Acid Applications

Boric acid's unique combination of mild acidity, flux properties, and flame-retardant action makes it indispensable in glass manufacturing, chemical processing, metallurgy, water treatment, and air pollution control.

Key Industry Applications

Boric acid is one of the most widely used boron compounds, valued for its unique combination of chemical properties.

Application 01

Glass & Ceramics

Boric acid is a key raw material in the production of borosilicate glass, fibreglass, and ceramic glazes. It enhances thermal resistance and chemical durability, making it essential for lab glassware, display substrates, and high-performance ceramic coatings.

  • Borosilicate glass (Pyrex, labware, optical glass)
  • Fibreglass insulation and textile composites
  • Ceramic tile, sanitaryware, and enamel glazes
  • Porcelain and fine china manufacturing
Application 02

Flame Retardants

Boric acid suppresses combustion and reduces smoke generation in a range of cellulosic and polymer materials. Its effectiveness as an environmentally friendly flame retardant makes it a preferred choice in construction and textile applications.

  • Cellulose insulation and wood treatment
  • Cotton, textile, and paper fireproofing
  • Flame-retardant coatings and formulations
Application 03

Chemical Manufacturing

Boric acid acts as a catalyst, reagent, and intermediate compound in numerous chemical processes. It stabilises chemical systems and prevents corrosion, making it valuable in industrial synthesis and chemical engineering.

  • Catalyst in organic synthesis reactions
  • Intermediate in boron compound production
  • Corrosion inhibitor in cooling systems
  • Stabiliser in chemical formulations
Application 04

Metallurgy & Mining

In metallurgical applications, boric acid acts as a flux and corrosion inhibitor. It is used in soldering, brazing, and welding operations to improve metal flow and bonding, as well as in surface treatment processes.

  • Flux agent in soldering and brazing
  • Corrosion inhibitor in metal treatment
  • Surface preparation and plating baths
  • Sintering aid in powder metallurgy
Application 05

Water Treatment

Boric acid is used in water treatment for pH control, boron supplementation, and chemical stability. It acts as a coagulant to enhance pollutant capture without introducing added toxicity, making it suitable for industrial and municipal water treatment systems.

  • pH adjustment and buffering in water systems
  • Boron supplementation in recirculating water
  • Coagulant aid for pollutant removal
  • Cooling tower water treatment
Application 06

Air Pollution Control

Boric acid is used in air pollution control applications to neutralise emissions, suppress dust, and reduce sulphur dioxide (SO₂) releases. It improves air quality in industrial exhaust treatment systems and helps meet environmental compliance standards.

  • Neutralisation of acid gas emissions
  • SO₂ reduction in flue gas treatment
  • Dust suppression in industrial facilities
  • Scrubber solutions for emission control
