Description

Potassium Aluminum Fluoride is an inorganic salt primarily used as a fluxing agent in metallurgical processes. Its value lies in its ability to lower the melting point of oxides and remove impurities, thereby improving metal quality and production efficiency. This compound is essential for manufacturers in the aluminum, ceramics, and abrasives industries seeking to optimize their smelting and sintering operations.

Application

• Primary flux in the secondary aluminum smelting industry to lower melting temperatures and improve metal recovery.
• Fluxing agent in the production of abrasives, such as aluminum oxide and silicon carbide, to facilitate bonding.
• Additive in ceramic glazes and enamels to modify melting characteristics and surface properties.
• Component in the manufacture of welding rod coatings and brazing fluxes.
• Used in the production of certain types of glass and optical crystals.
• Intermediate in the synthesis of other complex fluoride salts and catalysts.

Quality Control

Our Potassium Aluminum Fluoride is manufactured under strict process controls to ensure batch-to-batch consistency and high performance. Quality is verified through a series of analytical tests including assay, moisture content, and particle size distribution. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your technical requirements.

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 each use to prevent caking and degradation from atmospheric moisture. Keep away from strong alkalis.
