Shelf life
One year in sealed original packaging under the recommended storage conditions.
Packaging
1,360 kg IBC
Handling & Protection
Use controlled transfer with local extraction where mist can form. Wear chemical-resistant gloves and eye protection, avoid skin and eye contact and prevent antimony-containing releases to drains or surface water.
What Is Metal Passivator?
This metal passivator is an antimony pentoxide dispersion intended for refinery catalyst metal-passivation evaluation. The active component is Sb2O5, CAS 1314-60-9, with molecular weight 323.52 g/mol. The complete aqueous dispersion has no single molecular formula or molecular weight.
The supply specification controls Sb2O5 at 26.0–28.0%, sodium at ≤500 ppm, pH at 4.00–6.00 and density at 1.30–1.40 g/cm³ at 20°C. Viscosity is 3–8 cP at 20°C. These properties support receiving checks, transfer-equipment selection and process trials.
Aqueous antimony pentoxide metal-passivation additives are used to reduce the effects of nickel deposited on FCC catalysts. Selection and treatment should follow the refinery and catalyst operating procedure, considering feed metal burden, catalyst condition, injection design and compatibility. This chemistry should be evaluated as a catalyst-passivation additive rather than assumed to be an oil-soluble fuel-stability additive.
The matched concentration reference is an approximately 27% aqueous antimony pentoxide sol, which is not regulated as dangerous goods. Protect the dispersion from freezing and contamination and retain the original packaging closures. The specified shelf life is one year with first-in, first-out stock rotation.

Metal Passivator Applications
FCC nickel passivation
Antimony pentoxide dispersion for evaluation in fluid catalytic cracking catalyst systems affected by nickel deposition. Determine treatment and injection conditions using catalyst guidance and the refinery operating procedure.
Refinery metal-management trials
Controlled Sb2O5 concentration supports refinery trials evaluating catalyst activity, selectivity and metal contamination. Measure performance in the operating unit before fixing a treatment program.
Catalyst-additive formulation
Aqueous inorganic dispersion for compatible industrial catalyst-additive systems. Assess dispersion stability, sodium tolerance and process compatibility before blending or scale-up.

Metal Passivator FAQ
Which Metal Passivator grade should I choose?
Compare Sb2O5 26.0–28.0% against your process requirements. Check the TDS for assay and impurity limits, then test a sample for compatibility and performance in your process.
Can I request a Metal Passivator sample for testing?
Request a free sample for testing. Tell us the intended Antimony pentoxide sol application, preferred grade and the tests you plan to perform, so that we can arrange a suitable evaluation sample and technical information.
How is Metal Passivator packed and shipped?
Standard packing is 1,360 kg IBC. The usual MOQ is 1,000 kg, with a lead time of approximately 14 days from order confirmation. The reference bulk transport classification is Non-dangerous goods.
Which documents are available for Metal Passivator?
The TDS covers supply specifications; the reference SDS covers safety and transport. Both can be downloaded on this page. A batch COA can be provided with supply. Request documents for the grade and physical form you are ordering.
