Versatile Industrial Applications

Boric Acid Powder is a crucial ingredient in the glass and ceramics industries, agriculture as a micronutrient, and pharmaceuticals for its antiseptic properties. Its broad utility as an insecticide, laboratory reagent, and in metallurgy highlights its multifunctional nature.

Quality, Purity, and Safety

Meeting stringent international and Indian standards, this boric acid has a purity of at least 99%. It is securely packed in HDPE bags with an inner liner to prevent contamination and maintain freshness, ensuring a product shelf life of up to three years when stored correctly.

Ease of Use and Handling

The fine white powder passes through 150 mesh, ensuring consistent texture and quick solubility in various mediums. Its non-flammable and relatively non-toxic nature (when used as directed) makes it suitable for both industrial and laboratory environments.

FAQ's of Boric Acid Powder:

Q: How should boric acid powder be stored to maintain its quality?

A: Boric acid powder should be stored in a cool, dry place in a tightly closed container, ideally in the original HDPE packaging. This prevents moisture absorption and contamination, preserving its quality for up to three years.

Q: What is the main benefit of using boric acid powder in the glass and ceramics industries?

A: Boric acid powder enhances thermal and chemical stability in glass and ceramic products. It acts as a flux, reduces melting temperatures, and improves the mechanical strength and durability of finished goods.

Q: Where can boric acid powder be used in everyday life?

A: Aside from industrial usage, boric acid powder is used in households as an insecticide, antiseptic, and cleaning agent. Its effectiveness and mild nature make it valuable in these everyday applications.

Q: What precautions should be taken while handling boric acid powder?

A: Although boric acid powder is non-toxic in controlled quantities, it can be harmful if ingested in large amounts. Always use personal protective equipment like gloves and masks in industrial or laboratory settings, and keep the product away from food and children.

Q: How is boric acid powder typically applied in agriculture?

A: In agriculture, boric acid serves as a source of boron, an essential micronutrient for plant growth. It is applied in controlled low doses to correct boron-deficient soils, helping to improve crop yield and quality.

Q: What makes boric acid suitable for laboratory use?

A: Boric acid's high purity, predictable pH, and solubility make it suitable for buffer preparation, analytical chemistry, and as a standard laboratory reagent. Its consistent quality ensures reliable laboratory performance.
