Description

Tetraborate is an inorganic boron compound with versatile chemical functionality, serving as a crucial source of borate ions. Its value lies in its role as a stable and effective buffering and complexing agent in numerous industrial processes. This product is essential for manufacturers in the glass, ceramics, detergent, and agricultural industries, where precise boron content and chemical consistency are critical for product performance and quality control.

Application

• Glass & Ceramics Manufacturing: Acts as a flux to lower melting temperatures and improve the thermal and chemical durability of glass, fiberglass, and ceramic glazes.
• Detergents & Cleaning Agents: Functions as a water softener, builder, and bleach stabilizer, enhancing cleaning efficiency and preventing redeposition of dirt.
• Agriculture: Used as a micronutrient fertilizer and soil amendment to correct boron deficiencies in crops, promoting healthy growth and yield.
• Wood Preservation: Serves as a key component in borate-based treatments to protect lumber from fungal decay and insect damage.
• Flame Retardants: Incorporated into materials like plastics, textiles, and cellulose insulation to impart fire-resistant properties.
• Metallurgy: Employed as a flux in welding and soldering, and in metal refining processes to remove impurities.
• Adhesives & Sealants: Used as a cross-linking agent and stabilizer to improve the performance and shelf-life of various formulations.

Quality Control

Our Tetraborate is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Quality is verified through a series of analytical tests including assay, impurity profiling, and physical property checks. Certificates of Analysis (COA) documenting compliance with agreed specifications are 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 nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking and degradation.
