Keep the main technical questions distinct in an industrial quicklime enquiry. This white calcium oxide CaO powder is described as industrial quicklime with stated purity ≥95%, for steelmaking and chemical-process assessment of the actual proposed grade.
Confirm the chemical evidence for the sample
Request a current assay with the impurities relevant to the plant's acceptance limits. The ≥95% figure is a minimum threshold rather than an exact analysis. Keep the proposed material reference with the chemical results so the grade being compared remains identifiable.
Define powder grading through its own measurement
Ask for the particle or sieve report and method where physical grading matters. White appearance does not provide a numerical whiteness value, and powder form does not establish a mesh fraction. Agree the physical criteria needed for the actual evaluation.
Resolve the activity test basis
Clarify what the 420ml designation measures, including the conditions and endpoint. Obtain the complete procedure and result before interpreting activity or comparing it with another material. Similar wording is not sufficient evidence of equivalent measurements.
Connect the evidence to plant acceptance
Review current technical and safety documentation and agree a representative steelmaking or chemical assessment. Compare the chemical, physical and method-defined activity results for the same offered powder. Retain the criteria, conditions and observations with the tested sample reference. No verified high-reactivity ranking, numerical optical performance or universal operating result is established by the minimum assay and activity designation alone.
