Calcium fluoride granules primarily originate from natural fluorite minerals and serve as a vital fluoride raw material, appearing as white or colorless crystalline structures. It functions as a key fluxing agent in the metallurgical industry, while high-purity products form the material foundation for manufacturing optical components, specialty glass, and fluorine-containing chemicals.
We supply calcium fluoride granules in multiple specifications ranging from metallurgical to optical grades. Particle size and purity can be customized to meet your specific process requirements. For inquiries regarding specific technical specifications or sample requests, please contact us.
High calcium fluoride content with controlled impurities
Uniform particle size and excellent flowability
Chemically stable with acid and alkali resistance
Low UV absorption and high light transmittance
Metallurgical Flux Agent: In steelmaking and aluminum alloy smelting, it effectively lowers slag melting points, improves fluidity, and performs desulfurization and dephosphorization purification, significantly enhancing metal quality and smelting efficiency.
Foundational Fluorochemical Raw Material: Serves as the core starting material for producing hydrofluoric acid, aluminum fluoride, synthetic cryolite, and other fluoride products, critical for the stable operation of the entire fluorochemical industry chain.
Optical and Laser Materials: High-purity, low-defect calcium fluoride crystals are ideal for manufacturing UV and IR optical lenses, windows, and laser substrates, offering excellent light transmission and low nonlinear effects.
Ceramic and welding flux: In ceramic glazes, it functions as a fluxing agent to reduce firing temperatures. In welding processes, it serves as a flux component to stabilize the arc and remove oxides from weld seams.
Q1: What are the main differences between metallurgical-grade and optical-grade calcium fluoride particles?
A1: The core distinction lies in purity and specific impurity content. Optical-grade imposes extremely stringent limits on impurities like transition metal ions and hydroxyl groups to ensure superior optical performance. Metallurgical-grade focuses more on primary calcium-fluorine content and impurities affecting slag properties, such as silica.
Q2: What precautions are required for storage and transportation of this product?
A2: Although relatively chemically stable, this product must be stored in sealed packaging in a dry, well-ventilated area to prevent moisture absorption, caking, and contamination by other chemicals. Avoid co-loading with acidic substances during transportation.
Q3: Is calcium fluoride an environmentally sensitive substance?
A3: Calcium fluoride itself has low solubility and weak environmental mobility. However, it may release fluoride ions under acidic conditions or high-temperature processing. Handling and disposal must comply with relevant industrial solid waste management regulations to prevent long-term ecological impacts.
Q4: Can you provide products with specially cleaned surfaces (e.g., acid-washed)?
A4: Yes. We offer deeply purified particles to further reduce surface contaminants and trace metal impurities, meeting applications with stringent cleanliness requirements such as high-end optical coating materials.
