Ferric Chloride, also known as iron(III) chloride, is a highly soluble inorganic salt widely used as an industrial coagulant and precision etching agent. In water and wastewater treatment, it hydrolyzes to form ferric hydroxide flocs that adsorb suspended solids and phosphorus compounds, while in metal processing and electronics manufacturing it functions as a controlled chemical etchant for copper and related alloys, with performance governed by concentration, temperature, and solution chemistry (CAS 7705-08-0). For industrial supply requirements, the material is available with competitive factory pricing, customized specifications, complete documentation including MSDS, TDS, COA, and options for bulk or solution supply.

Usage: Mainly used for metal etching, sewage treatment. Among them, etching includes etching of copper, stainless steel, aluminum and other materials, which has the advantages of good effect and cheap price for raw water treatment with low oil content, but brings the disadvantage of yellowing of water color. It is also used for printing and dyeing roller engraving, electronic industry circuit board and fluorescent digital cylinder production, etc. The construction industry is used to prepare concrete to enhance its strength, corrosion resistance, and water resistance. It can also be formulated with ferrous chloride, calcium chloride, aluminum chloride, aluminum sulfate, hydrochloric acid, etc. to make a waterproof agent for mud condensation, and is used in the inorganic industry to make other iron salts and inks. The dye industry uses it as an oxidizing agent when dyeing indigo dyes. The printing and dyeing industry is used as a mordant. It is used in the metallurgical industry as a chlorination invasion agent for the extraction of gold and silver. The organic industry is used as a catalyst, oxidizer, and chlorinating agent. The glass industry is used as a thermal colorant for glassware. It is used in the soap industry as a coagulant for the recovery of glycerol from soap waste liquids.
FAQ - Technical & Supply Chain
-
Q:
