Description
Cerium Chloride 20% Solution
Aqueous cerium(III) source for materials and coating formulations. Draft assumption: water is the solvent; the requested 20% designation is retained, but its reporting basis (w/w or w/v; CeCl₃, Ce or CeO₂ equivalent) should be confirmed before process use.
Cerium Chloride Solution, also known as cerous chloride solution, provides cerium(III) in a liquid format for water-compatible processing. Cerium chloride is used in ceria synthesis and studied in coating and corrosion-inhibitor systems.
Product profile
- Name : Cerium(III) Chloride Solution
- Synonym : Cerous chloride solution
- Solute Formula : CeCl₃
- Solute CAS No. : 7790-86-5 (anhydrous cerium chloride identity)
- Declared Concentration : 20% — reporting basis to be confirmed
- Solvent : Water (assumed; confirm against approved specification)
- Physical Form : Liquid; colour and clarity to approved specification
- pH / Density / Free Acid : Product-specific values required; not assumed
Identity references relate to the anhydrous solute and do not describe the complete aqueous mixture. This is a solution, not an anhydrous solid; no solution molecular weight or solid-state density is assigned.
Applications
- Ceria and materials synthesis — dissolved cerium feedstock for compatible wet-chemical preparation of cerium oxide and related materials.
- Coating development — reported as a precursor for cerium oxide thin films and cerium-based coatings.
- Corrosion-inhibitor research — studied in selected metal/substrate and electrolyte systems; results depend on substrate and conditions.
These are literature-supported application areas, not validation of this 20% formulation. Working concentration, acidity, substrate compatibility and performance must be established for each process. This solution is not a ready-to-use coating bath and is not a direct substitute for anhydrous cerium chloride in water-sensitive chemistry.
Handling & Storage
Avoid skin/eye contact and breathing mist. Use suitable ventilation, gloves and eye/face protection. Prevent release to drains or the environment. Store tightly closed in compatible containers with secondary containment. Follow the supplied solution SDS for storage limits, incompatibilities and spill response. The exact mixture SDS has not yet been provided; hazard labels and transport classification must be assessed for the supplied concentration and any free acid.
Request a Quotation
Discuss your application with Sontara Organo Industries. Share the required concentration basis, impurity limits and quantity for specification review and a quotation. Request the approved specification, current SDS and batch COA for evaluation.
For professional chemical use. Refer to the approved specification and product SDS. No pharmaceutical, food, drinking-water-treatment or ready-to-use corrosion-protection approval is implied.
