Description

Diammonium Tetraborate CAS NO 12007-58-8 is an inorganic ammonium salt of boric acid, valued for its role as a source of both boron and ammonia in specialized industrial processes. This compound is particularly significant for its utility in applications requiring controlled release of these components under specific thermal or chemical conditions. It is primarily needed by manufacturers in the ceramics, flame retardancy, and specialty chemical synthesis sectors.

Application

• As a fluxing agent and glass former in the production of specialty ceramics and enamels.
• As a component in flame-retardant formulations for textiles, plastics, and wood products.
• As a boron and nitrogen source in the synthesis of advanced boron nitride precursors and other inorganic materials.
• In analytical chemistry as a reagent or standard for boron determination.
• In the formulation of corrosion inhibitors and metal treatment solutions.
• As a cross-linking agent or catalyst in specific polymer and resin systems.

Quality Control

Our Diammonium Tetraborate is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and physical characterization, to meet exacting customer and industry specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent caking and degradation from atmospheric moisture.
