What is Ferric Chloride Hexahydrate Used for?
Why choose ferric chloride hexahydrate?
- Superior Operational Safety: Extremely gentle dissolution process.
- Rapid & Total Solubility: Instant dissolution, no impurities.
- High Purity for Fine Industries: Chemically stable, with strict heavy metal control.
- Precise Dosing & Handling: Physically stable, less prone to dust generation.
What is Ferric Chloride Hexahydrate Used for?
- Water Treatment: It acts as a highly effective coagulant and flocculant, removing suspended solids, phosphates, heavy metals, and colloidal particles from both drinking water and wastewater.
- Industrial Etching: It’s a primary etchant for copper in printed circuit board (PCB) manufacturing and for engraving metals, dissolving unwanted metal precisely.
- Chemical Synthesis: It serves as a versatile catalyst (e.g., in Friedel-Crafts reactions) and a common oxidizing agent or precursor in organic and inorganic chemistry.
- Electroplating Protection: It’s used to produce chromate conversion coatings on aluminum, zinc, and cadmium, enhancing corrosion resistance and paint adhesion before plating or painting.
FAQ of Ferric Chloride Hexahydrate
No. While both are iron(III) chlorides, Hexahydrate (FeCl3 · 6H_2O$) contains water molecules in its crystal structure and has a lower iron content (approx. 20%). Anhydrous (FeCl3) is water-free, higher in purity (96%+), and reacts more violently when dissolved.
It is an excellent phosphorus remover and sludge conditioner. When added to wastewater, it forms dense hydroxide flocs that quickly settle, effectively removing heavy metals, suspended solids, and reducing the Chemical Oxygen Demand (COD).
Yes, it is acidic and highly corrosive to most metals and skin. Proper PPE, including acid-resistant gloves and goggles, is mandatory during handling. Always add the chemical to water (not water to chemical) when preparing solutions.
HDPE plastic drums with corrosion-resistant seals.
Store in a cool, dry, well-ventilated place, away from strong oxidizers and alkali metals.
