White powder is the supplied appearance described for this industrial calcium oxide quicklime. Stated purity is ≥95%, with steelmaking and chemical-material enquiries requiring a matched set of chemical, physical and activity evidence before qualification.
Keep three material questions distinct
The assay identifies the reported chemical grade, while the particle report describes the proposed powder specification. Activity requires its own test method and conditions. None of these records should be replaced by a general active-quicklime description or a qualitative colour name.
- Chemical evidence
- Current sample-linked assay and relevant impurity criteria.
- Physical evidence
- Defined supplied form, particle measurements and test basis.
- Activity evidence
- Procedure, conditions, endpoint and actual material identifier.
Clarify the meaning of the 420ml designation
Ask what the volume represents and how it is measured for the proposed grade. Keep the full method with any reported result so comparisons concern equivalent tests. The designation alone does not establish a reactivity rate or a numerical whiteness value.
Match the powder to the industrial acceptance brief
Describe the steelmaking or chemical process and its material requirements before arranging a representative assessment. Review matched technical and safety documentation, then record the criteria and conditions used to judge the grade. No universal process benefit or operating recipe is established here. Retain the tested material identity and evidence set so a repeat enquiry can identify the actual quicklime evaluated and any changed plant requirement.
