Description

Calcium Pentafluoroaluminate is an inorganic fluoride salt with the molecular formula CaAlF5. This specialized compound is valued for its role as a critical fluxing agent and a source of fluoride ions in high-temperature industrial processes. It is primarily utilized in sectors such as metallurgy, ceramics, and advanced material synthesis where precise control over melting points and slag chemistry is required.

Application

• Aluminum Electrolysis: Used as a key component in the electrolyte bath to lower operating temperatures and improve current efficiency.
• Ceramic & Glass Manufacturing: Acts as a flux to reduce melting temperatures and modify the thermal and optical properties of final products.
• Metallurgical Fluxes: Employed in steel and non-ferrous metal processing to remove impurities and control slag fluidity.
• Welding Rod Coatings: Incorporated as a flux ingredient to stabilize the arc and improve weld quality.
• Optical Crystal Growth: Serves as a starting material or dopant in the synthesis of specialized fluoride crystals for lenses and windows.
• Laboratory Reagent: Used in research and development for inorganic synthesis and as a fluoride source in specific chemical reactions.

Quality Control

Our Calcium Pentafluoroaluminate is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a series of analytical tests including assay, moisture content, and particle size distribution. A Certificate of Analysis (COA) documenting all critical parameters is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture.
