Confirm which properties support the grade comparison before planning a quicklime evaluation. This industrial calcium oxide CaO is described as white quicklime powder with stated purity ≥95%, for steelmaking and chemical-industry enquiries about the actual proposed material.
What supports the chemical comparison?
Request a current assay and relevant impurity results for the offered sample. Compare them with the plant's required chemical limits. The ≥95% purity is a stated minimum rather than an exact sample composition or a complete acceptance specification.
What supports the physical comparison?
Ask for particle or sieve measurements and their method if powder grading matters to the operation. White appearance does not supply a numerical whiteness value. Powder form also does not define a mesh fraction, so agree the physical criteria independently.
What supports the activity comparison?
Clarify what 420ml measures and obtain the complete test conditions, endpoint and procedure. Keep the result with its method; similar high-reactivity wording alone does not establish a verified rate or equivalent test performance.
What supports the plant decision?
Review current technical and safety documents and assess a representative grade against the actual steelmaking or chemical acceptance brief. Link the chemical, physical and method-defined activity reports to the same material. Retain the sample identity, conditions and observations for future enquiries. No numerical optical performance, universal operating recipe or guaranteed process result is established by the minimum assay and activity designation alone.
