A technical material proposal should identify the exact quicklime being assessed. This industrial calcium oxide is described as white CaO powder with stated purity ≥95%, for steelmaking and chemical-industry enquiries requiring further qualification.
Match the proposed specification to the reports
Request a current assay and the relevant physical powder information under the actual grade identifier. Keep the ≥95% minimum distinct from an exact sample analysis. Confirm which impurity limits and particle methods the intended plant uses for material acceptance.

Clarify the activity wording before comparing grades
Ask what the 420ml designation measures and obtain the procedure, conditions and endpoint associated with the result. Similar activity descriptions cannot establish equivalent reactivity when the methods differ or remain undefined. White appearance also does not provide a numerical optical measurement.
Keep application qualification specific
Describe the steelmaking or chemical process and the criteria used to judge the material. A general industrial-use name does not supply operating conditions or demonstrate a result in a particular installation.
Retain the evidence supporting the material decision
Review matched technical and safety documentation before a representative plant assessment. Record the actual grade, methods and qualification observations together; no verified reactivity ranking or universal process improvement is established here. Use that evidence set in repeat enquiries so changed powder specifications or plant requirements can be distinguished from the quicklime originally evaluated.
