Applications
1. For Water And Wastewater Treatment: Ferric chloride hexahydrate (FeCl₃·6H₂O, CAS 10025-77-1) is a highly effective coagulant and flocculant for municipal and industrial wastewater treatment, removing turbidity, suspended solids and phosphates, and supporting sludge dewatering for cleaner discharge and process water.
2. For PCB And Metal Etching: In the electronics industry, ferric chloride hexahydrate is a standard etching agent for printed circuit boards and metal surface treatment, providing controlled, uniform etching of copper and other metals for precision manufacturing.
3. For Organic Synthesis And Catalysis: As an iron-based Lewis acid salt, ferric chloride hexahydrate serves as a catalyst and oxidant in organic synthesis reactions, supporting dye, pigment and fine chemical production processes.
4. For Dyeing Pigment And Iron Salt Manufacturing: The compound is used as an oxidant and mordant in the dye industry and as a raw material for producing iron-based pigments and other iron salts, giving chemical manufacturers a versatile iron source.
5. Reliable Supply For Global Industry: Supplied in high-purity crystalline form with consistent quality, ferric chloride hexahydrate gives water treatment plants, electronics makers and chemical manufacturers a dependable iron salt with stable supply, flexible packaging and professional technical support.
Quality Assurance
Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.
Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
