Calcium Fluoride

Product Specification

Feature

High-purity calcium fluoride (fluorspar powder/balls) covers multiple grades from 70% to 97%, with clearly controlled key impurity indicators (the 97% grade has total impurities below 0.5%, iron below 0.03%, silicon below 0.2%, and sulfur and phosphorus strictly specified), effectively avoiding insufficient fluxing, steel sulfur pickup, equipment corrosion and crystal color centers caused by purity-application mismatch and excessive impurities; the 70%–75% grade keeps active content variation within ±1.5%, better than the common ±3% in the industry, ensuring high batch-to-batch stability so customers need not frequently adjust formulas or shut down furnaces for cleaning; in cement production it lowers clinker firing temperature by 30–50°C and raises kiln output by about 8%–12%, in general casting it cuts slag cleaning time by about 20% and saves 15%–25% of flux cost per ton of hot metal, and in carbon steel smelting it improves desulfurization efficiency by about 10%, raises steel yield by about 2%–3% and reduces furnace buildup frequency by about 30%; the 96% grade achieves over 96% acidolysis conversion as raw material for hydrofluoric acid production, with about 10% less waste acid residue than the 95% grade; the 97% grade delivers over 90% transmittance at 0.2–8μm in synthetic fluorite crystals with about 15% higher qualification rate than 96% material, lowers sintering temperature by 50–80°C, raises density by 5%–8% and improves flexural strength by about 12% in specialty ceramics, and is also suitable for advanced treatment of fluoride-containing wastewater by removing fluoride ions via crystallization-precipitation; deeply engaged in fluorochemicals and serving metallurgy, chemicals and building materials, the company provides supporting technical services to help customers optimize usage and reduce total cost.
