Description
Barium chloride dihydrate (BaCl2·2H2O, CAS 10326-27-9) is an inorganic barium salt supplied as a white crystalline solid. It carries no E-code designation and is also referenced under the common abbreviations BaCl2.2H2O and bariumdichloridedihydrate. It is registered under REACH and assigned EC number 600-412-6.
In water treatment, barium chloride precipitates sulfate ions as insoluble barium sulfate, removing them from process streams and brine circuits. In textile and leather processing, it acts as a mordant and fixative, binding dyes to fibres through ionic interaction. It also serves as a catalyst precursor and flame-retardant additive in selected industrial formulations.
Barium chloride dihydrate is available in technical and industrial grades, typically supplied in 25 kg bags or bulk quantities. The substance is subject to REACH registration requirements and classified as hazardous under CLP regulations, requiring compliant SDS documentation. Buyers should confirm grade specifications against their process requirements prior to ordering.
