The evidence used in an enquiry should remain linked to the powder evaluated. This industrial white quicklime is calcium oxide CaO powder with stated purity ≥95%, for steelmaking and chemical-industry assessment against the needs of the intended operation.
Keep the proposed grade identifiable in the analysis
Request a current sample assay with the relevant impurity results and material reference. The ≥95% purity is a minimum rather than an exact composition. Compare the complete chemical results with the plant's agreed acceptance limits before drawing a grade conclusion.
Add physical evidence under the same reference
Ask for particle or sieve measurements if grading is part of the evaluation. White powder describes form and appearance; it does not define a mesh fraction or a numerical whiteness value.
Keep the activity result attached to its method
Clarify which quantity, conditions and endpoint support the 420ml designation. Obtain the full procedure as well as the result. Similar activity wording alone does not establish that measurements from different materials are directly comparable or demonstrate a verified reactivity ranking.
Carry the report set into the plant review
Use current technical and safety documentation when agreeing a representative steelmaking or chemical assessment. Review the chemical, physical and method-defined activity evidence together, then retain the tested material identity with the actual criteria and observations. Keep those references available for later material discussions. No universal operating recipe, numerical optical performance or guaranteed process result follows from the minimum purity and activity designation alone.
