Zinc Chloride Specification

Differences Between Industrial Grade and Battery Grade Zinc Chloride:

  • Purity Standards: Battery Grade has stricter purity requirements with iron (Fe) ≤0.0005% and lead (Pb) ≤0.0005%, while Industrial Grade allows higher impurity levels (Fe ≤0.001-0.002%, Pb ≤0.001-0.002%).

  • Zinc Corrosion Test: Battery Grade must pass the zinc sheet corrosion test, which is not required for regular Industrial Grade.

  • Main Application: Battery Grade is specifically designed for dry cell batteries as electrolyte to improve conductivity. Industrial Grade is used for catalysts, metal treatment, textile processing, and water treatment.

  • Oxychloride Control: Battery Grade maintains tighter control of oxychloride (ZnO) content (1.8-2.2%) compared to broader limits for lower industrial grades.

  • Quality Consistency: Battery Grade offers more consistent quality for sensitive electrochemical applications, while Industrial Grade provides flexibility for general manufacturing use.

Zinc Chloride

  • We Supply Both Industrial and Battery Grade: We offer Zinc Chloride in both grades to match your exact needs — Industrial Grade for general manufacturing and Battery Grade with stricter purity for sensitive electrochemical applications.

  • Battery Grade Meets Strict Purity Standards: Our Battery Grade has very low heavy metals (Fe ≤0.0005%, Pb ≤0.0005%) and passes the zinc sheet corrosion test, ensuring reliable performance in dry cell batteries.

  • Industrial Grade for Wide Applications: Industrial Grade delivers consistent quality for metal treatment, wood preservation, soldering flux, textile processing, and water treatment at a cost-effective price.

  • Versatile Multi-Industry Solution: Zinc Chloride serves as an essential chemical across many sectors — catalyst in organic synthesis, electrolyte in batteries, flux in metalworking, and flame retardant in wood treatment.

  • Full Quality Documentation Provided: Every shipment comes with a Certificate of Analysis (CoA) confirming purity and specifications. We provide professional export documentation for smooth customs clearance worldwide.

What is Zinc Chloride Used for

  • For Chemical Synthesis: It serves as a catalyst (e.g., in Friedel-Crafts reactions) and a dehydrating agent in organic synthesis, and is used to produce organic zinc reagents.

  • In the Textile Industry: It functions as a mordant for dye fixing, a weighting agent, and a solvent for cellulose in fiber production.

  • In Batteries: It acts as the electrolyte in zinc-carbon dry cells.

  • In Metal Treatment: It is used as a flux to remove oxides for soldering and as a pretreatment agent in electroplating.

  • For Wood Preservation: It imparts antiseptic and flame-retardant properties to wood.

  • In Pharmaceuticals: In low concentrations, it is utilized for its astringent and antiseptic properties in certain medicinal formulations.

  • In the Petroleum Industry: It is employed as a purifying agent.

  • In Paper & Inks: It is used in the manufacture of blueprint paper and as a preservative in inks.

FAQ of Zinc Chloride

No. Our zinc chloride is industrial and battery grade only, not food grade. Industrial grade is toxic and corrosive — it causes severe skin burns and eye damage, and is harmful if swallowed. Only high-purity food grade (meeting standards like GB 1903.34-2018) can be used as a nutrient supplement, which we do not supply.

Yes, it is highly hygroscopic. Store under inert gas in a cool, dark place (<15°C recommended) and keep containers tightly sealed to prevent moisture absorption.

Yes. It is classified as Class 8 corrosive, UN 2331, Packing Group III. It causes severe skin burns and eye damage (H314), and is harmful if swallowed (H302) .
