Description

Barium Chloride Dihydrate — High-Purity Chemical for Pigments, Metallurgy & Water Treatment

Barium chloride dihydrate occupies a specialized niche in the industrial chemical landscape, serving as a critical raw material in the manufacture of specialty pigments, a hardening agent in metallurgical heat treatment, and a precision chemical reagent in analytical laboratories. The toxicity of soluble barium compounds imposes strict handling and documentation requirements that differentiate barium chloride procurement from general chemical sourcing. Davar ChemTech, based in Vadodara, Gujarat, supplies barium chloride dihydrate to industrial consumers who require guaranteed purity, compliant packaging, and detailed safety documentation with every shipment.

Procurement professionals sourcing barium chloride must navigate a unique set of considerations centered on regulatory compliance and workplace safety. Barium chloride is classified as a toxic substance (H351 — suspected of causing cancer; H301 — toxic if swallowed) under GHS classification, and its handling is governed by specific occupational exposure limits and environmental discharge regulations. This means that packaging must be child-proof and tamper-evident, transport documentation must include complete toxic substance declarations, and end users must maintain detailed usage and disposal records. Davar ChemTech’s experience in toxic chemical distribution ensures that every consignment meets these regulatory requirements, protecting both the customer and the supplier from compliance gaps.

Industrial Applications

Specialized Industrial Usage

The most significant industrial application of barium chloride is in the production of barium sulfate pigments, specifically lithopone (a co-precipitate of barium sulfate and zinc sulfide) and blanc fixe (precipitated barium sulfate). These pigments are valued for their excellent hiding power, chemical inertness, and non-toxicity in the finished pigment form. The manufacturing process involves reacting barium chloride with sodium sulfate to precipitate barium sulfate of controlled particle size and morphology. The quality of the starting barium chloride directly determines pigment characteristics: high-purity barium chloride with minimal iron and heavy metal contamination produces brighter, cleaner pigment colors, while impure material introduces unwanted hues that reduce pigment value. Davar ChemTech supplies pigment-grade barium chloride with tight impurity specifications that enable consistent pigment production quality.

In metallurgical applications, barium chloride is used as a component of salt bath heat treatment compositions for the case-hardening of steel components. Salt bath hardening provides uniform surface heating and precise control over the case depth and hardness of treated parts. The addition of barium chloride to the salt bath formulation lowers the operating temperature range and improves the bath’s thermal stability, reducing energy consumption and extending bath service life between maintenance intervals. Automotive and aerospace component manufacturers who rely on salt bath heat treatment require barium chloride with consistent composition, as variations in impurity levels can affect case-hardening kinetics and final component performance.

Water treatment facilities utilize barium chloride for sulfate removal from industrial wastewater streams, particularly in industries such as mining, chemical manufacturing, and pulp and paper where sulfate concentrations in effluent must be reduced to meet regulatory discharge limits. The addition of barium chloride to sulfate-laden wastewater produces insoluble barium sulfate precipitate that is removed by clarification or filtration. This application requires precise dosing control and high-purity barium chloride to avoid introducing secondary contaminants. The low solubility product of barium sulfate (Ksp = 1.1 x 10-10) ensures essentially complete sulfate removal when stoichiometric quantities of barium chloride are applied, making it an efficient treatment option for facilities facing stringent sulfate discharge requirements.

Technical Specifications

Storage, Handling & Safety

Barium chloride is a toxic substance and must be stored and handled with strict adherence to hazardous chemical safety protocols. Storage areas must be dry, well-ventilated, and physically segregated from food products, animal feed, and potable water sources. Containers must be tightly sealed and labeled with GHS-compliant hazard pictograms and signal words. Access to barium chloride storage areas should be restricted to authorized personnel only. Workers must wear full protective equipment including chemical-resistant gloves (nitrile or neoprene), chemical splash goggles, face shield, and protective clothing. Ingestion is the primary toxicological risk; barium chloride can cause severe gastrointestinal disturbance, muscle paralysis, and cardiac arrhythmia if swallowed. All food, beverages, and tobacco products must be excluded from handling areas. Spill cleanup should be performed using appropriate personal protective equipment; collected material should be disposed of as hazardous waste in accordance with local environmental regulations.

Supply & Compliance

Davar ChemTech’s Vadodara facility includes dedicated toxic substance storage zones equipped with containment berms, ventilation, and access controls as required by the Manufacture, Storage, and Import of Hazardous Chemicals (MSIHC) rules. We maintain valid hazardous chemical licenses and provide all necessary documentation with each shipment including test certificates, MSDS, GHS labels, and toxic substance transport declarations. Our customer base spans pigment manufacturers in Gujarat’s chemical zone, steel heat treatment facilities in Maharashtra and Karnataka, and analytical laboratories across India. Each customer receives the documentation package needed to comply with their own regulatory obligations, creating a seamless procurement experience.

Quality Assurance

Davar ChemTech’s quality assurance protocols for barium chloride are among the most rigorous in our product portfolio, reflecting the compound’s toxicological classification and the sensitivity of its end-use applications. Incoming material is tested for assay purity, strontium and calcium content, iron contamination, and heavy metal residues using atomic absorption spectroscopy. Each batch’s Certificate of Analysis provides quantitative data on these parameters, giving procurement teams the traceability needed for regulatory compliance and internal quality audits. Our commitment to documentation accuracy, packaging integrity, and safe handling practices has established Davar ChemTech as a preferred barium chloride supplier for quality-conscious industrial consumers.
