Description

Disodiumtetraboratetetrahydrate CAS NO 12297-20-0 is a specific hydrated form of sodium borate, a versatile inorganic salt. This compound is valued for its controlled release of boric oxide and its role as a consistent source of boron, a critical micronutrient and flame retardant component. It is essential for manufacturers in the glass, ceramics, agriculture, and flame retardant industries seeking reliable boron chemistry for their processes.

Application

• As a flux and glass-forming agent in the production of specialty glasses, fiberglass, and ceramic glazes.
• As a micronutrient fertilizer and soil amendment in agriculture to correct boron deficiency in crops.
• As a component in flame retardant formulations for textiles, plastics, and wood treatments.
• In the manufacture of detergents, cleaning agents, and water softening products.
• As a precursor or intermediate in the synthesis of other boron-based chemicals.
• In metallurgical processes as a flux for welding and brazing.
• For corrosion inhibition in cooling water systems and antifreeze solutions.
• In laboratory settings as a buffer component or for analytical chemistry applications.

Quality Control

Our Disodiumtetraboratetetrahydrate is produced under a stringent quality management system. Each batch is tested to ensure it meets precise chemical and physical specifications, including assay, heavy metal limits, and clarity of solution. Certificates of Analysis (COA) documenting purity and compliance with relevant industrial or technical grade standards are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep container tightly sealed when not in use to prevent caking or absorption of atmospheric moisture. Keep away from strong acids.
