Product Description

Product Description

Ferric chloride 41% Etching Grade

This product is a high-purity, dark brown aqueous solution of ferric chloride, with a concentration of 41%. It is specifically formulated as an "Etching Grade" chemical for industrial etching processes. Its main component, Ferric Chloride (FeCl3), possesses strong oxidizing properties, making it indispensable in the electronics and metalworking industries.

1.Core Application: Precision Etching
    PCB Etching:This is its most critical and widespread use. In printed circuit board (PCB) manufacturing, it efficiently and precisely etches away unprotected copper layers to form intricate circuit traces, serving as a fundamental material for the electronics industry.
    Metal Etching: Widely used for etching materials like stainless steel, copper, and alloys. It is essential for producing signage, precision metal parts, scales, and decorative art pieces.

2. Significant Application: Water Treatment Coagulant
    Functions as a highly effective inorganic coagulant in municipal and industrial wastewater treatment. The ferric hydroxide colloids formed upon its hydrolysis efficiently remove phosphorus, suspended solids, color, and heavy metals from water, achieving purification and phosphate removal goals.

3. Other Industrial Uses
    Acts as a catalyst (Lewis acid) in organic synthesis, such as in Friedel-Crafts reactions.
    Used as a doping agent in the semiconductor industry.
