The purity threshold should remain clear when assessing a calcium oxide offer. This industrial white quicklime powder is identified as CaO with stated purity ≥95%, for steelmaking and chemical-industry enquiries requiring evaluation of the proposed material.
Read the purity figure as a minimum
The ≥95% value is a lower limit rather than an exact analysis of every sample. Request a current assay for the actual grade and the impurities relevant to the operation. Compare that chemical evidence with the plant's required acceptance limits.
Define the physical grade needed for evaluation
Obtain the particle or sieve report and measurement method where powder grading matters. White appearance is qualitative and does not provide a numerical whiteness value. The powder name also does not establish a mesh fraction, so agree the actual physical criteria separately.
Clarify the activity description
Ask what the 420ml designation measures and obtain the complete procedure, conditions and endpoint. A high-reactivity label alone does not establish a verified rate or make activity results from different methods directly comparable.
Link the report set to the plant assessment
Keep chemical, physical and activity evidence under the same material reference. Review current technical and safety documentation and agree a representative steelmaking or chemical evaluation. Retain the tested sample identity with the criteria, conditions and observations for later enquiries. Neither minimum purity nor an undefined activity designation establishes a universal operating recipe, verified reactivity ranking or guaranteed process result.
