This industrial quicklime is described as white calcium oxide powder with stated purity ≥95%. Steelmaking and chemical-industry enquiries can use that identity as a starting point, then confirm the grade through the relevant material and plant evidence.
Confirm the minimum against a current sample
Request an assay that identifies the proposed material and its analytical basis. Keep the ≥95% minimum separate from the actual result for that sample. Define any additional impurity criteria required by the intended steelmaking or chemical process before judging the report.
Specify the physical powder being proposed
Ask for the particle specification and measurement method under the same grade identifier. A general white-powder description does not establish a mesh fraction, particle percentile or numerical whiteness. The physical evidence should concern the material actually offered for evaluation.
Define the activity method before comparison
Clarify the procedure, conditions and endpoint behind the 420ml activity designation, including what the volume represents. Retain that context with any result. Without it, the designation cannot establish a verified high-reactivity ranking between proposed quicklime grades.
Record the plant's material decision
Review matched technical and safety documentation and assess a representative material against agreed acceptance criteria. No operating recipe or universal process benefit is established here. Keep the sample, reports and qualification conditions together so a repeat enquiry identifies the quicklime evaluated and clearly records any changed plant or material requirement.
