Quicklime CaO with stated purity ≥95% is the industrial white powder for this steelmaking and chemical-process enquiry. A material decision requires both a defined powder acceptance record and evidence relevant to the actual plant specification.
Agree the chemical and physical acceptance records
Request the current assay and identify any impurity criteria required by the process. Keep the ≥95% minimum distinct from the measured sample result. Ask for the particle specification and method under the same grade identifier so the two reports describe one proposed material.
- Chemical acceptance record
- Assay, reporting basis, relevant impurity limits and sample identity.
- Physical acceptance record
- Supplied powder specification, particle method and the actual grade reference.
Make the activity report method-complete
For the 420ml designation, clarify what quantity is measured and obtain the procedure, conditions and endpoint. Similar volume descriptions cannot establish a verified reactivity comparison without equivalent methods. Retain the actual sample identifier with that report.
Assess the powder against the plant specification
Review matched technical and safety documentation before evaluating a representative material. Define the steelmaking or chemical-process criteria and record the conditions applied during qualification. No operating recipe or universal process benefit is established here. Keep the tested quicklime grade, reports and acceptance observations together so a repeat enquiry identifies the material evaluated and clearly distinguishes a changed powder specification or plant requirement.
