96% Boric acid CAS 11113-50-1

1. Product Overview

Boric acid (H₃BO₃, orthoboric acid) is a white, crystalline, odorless weak acid with a characteristic slippery feel — the simplest and most important boron compound of industry. It is the boron source of borosilicate glass and electronic glass fiber, the classic flame retardant of cellulose and textiles, an essential micronutrient fertilizer

One molecule, an unusual breadth of service: boric acid lowers the melting point and thermal expansion of glass to make heat-resistant laboratory ware and glass-fiber-reinforced circuit boards; it suppresses combustion of wood, paper and fabric; it corrects boron deficiency in crops and kills cockroaches and ants; it absorbs neutrons to control nuclear fission;

Core value propositions:

Glass & Glass Fiber:

● the boron source of borosilicate glass, electronic glass fiber and optical glass;

Flame Retardancy & Cellulose Treatment:

● a classic flame retardant for wood, cellulose, paper and textiles;

Agriculture & Pest Control:

● an essential micronutrient fertilizer and an effective household/structural insecticide;

2. Product Information (Quick Facts)

3. Chemistry & Properties

Boric acid is a weak, planar Lewis acid  in which the electron-deficient boron accepts a hydroxide ion to form the borate anion — the chemistry behind its buffering, antiseptic and boron-supply roles. On heating it dehydrates progressively to metaboric acid and finally to boron oxide (B₂O₃), the glass-forming oxide that gives borosilicate glass its low thermal expansion and chemical durability.

4. Key Features & Benefits

● Essential glass-former: delivers boron for low-expansion, heat-resistant borosilicate glass and electronic glass fiber.

● Effective cellulose flame retardant: suppresses smoldering and flame in wood, paper and textiles.

● Essential crop micronutrient: corrects boron deficiency — vital for flowering, fruit set and root health.

● Proven insecticidal action: effective, low-toxicity control of cockroaches, ants and wood-boring insects.

● Mild antiseptic and buffer: gentle preservation, disinfection and pH control in personal care.

● Versatile boron feedstock: precursor of borates, borate esters and boron chemicals.

5. Main Applications

5.1 Glass & Glass Fiber (Core Application)

Boric acid is the boron source of the glass industry:

● Borosilicate glass: heat-resistant laboratory ware, cookware and pharmaceutical glass (low thermal expansion);

● Electronic glass fiber: E-glass yarns and fabrics for copper-clad laminates and printed-circuit boards;

● Optical glass: boron-modified glasses with tailored refractive index;

● Ceramics and enamels: fluxing component of glazes, frits and enamel formulations.

5.2 Flame Retardancy & Cellulose Treatment

● Wood treatment: flame-retardant and preservative impregnation (often with borax);

● Cellulose insulation: fire-retardant treatment of loose-fill cellulose insulation;

● Textiles: flame-retardant finishing of fabrics and curtains;

● Paper and board: fire-retardant additive in specialty papers.

5.3 Agriculture & Pest Control

● Boron fertilizer: essential micronutrient for crops — flowering, fruit set, and cell-wall function;

● Insecticide: effective against cockroaches, ants, silverfish and wood-boring beetles;

● Wood protection: borate-based protection of structural timber against insects and decay;

● Soil and foliar application: soluble boron source for deficiency correction.

5.4 Specialty Applications

● personal care: mild antiseptic, eyewash buffer, skin-care

● Boron chemicals: feedstock for borates, borate esters, perborates and specialty compounds;

● Electroplating and metalworking: additive in plating baths and rust-inhibiting formulations.

8. FAQ

Q1: What is boric acid used for?

Boric acid is the boron source of borosilicate glass and electronic glass fiber; a classic flame retardant for wood, cellulose and textiles; an essential boron fertilizer and an effective cockroach/ant insecticide;

Q2: What is the difference between boric acid and borax (sodium borate)?

Both are boron compounds with similar flame-retardant and preservative uses, but they differ chemically: boric acid (H₃BO₃) is the acid form — the preferred boron source for glass, fiber and pH-sensitive applications; borax (Na₂B₄O₇·10H₂O) is the sodium salt — used for cleaning, buffering, glass and as a co-flame-retardant. Formulators often use them together in borate systems (e.g. borax/boric-acid wood treatment).

Q3: Is boric acid safe to handle?

Boric acid has low acute toxicity and long history of use, but under EU CLP it is classified as toxic to reproduction (Repr. 1B, H360FD), and cosmetic use is restricted by the EU SCCS. Use gloves, goggles and dust protection, avoid ingestion and inhalation of dust, and keep it away from food. It is an industrial chemical; agricultural, pharmaceutical and cosmetic use must comply with the destination market's regulations.
