The physical grade and chemical analysis should describe the same powder when reviewing an industrial quicklime offer. This white calcium oxide CaO material has stated purity ≥95% and is intended for steelmaking and chemical-process enquiries.
Relate the assay to your chemical limits
Use the minimum purity as an initial comparison point and request a current sample analysis for the actual proposed grade. Identify the relevant impurity limits in the plant brief. An overall assay alone does not answer every chemical requirement for a process.
Ask how the powder grade is measured
The white appearance and powder form provide a qualitative description. For a defined physical comparison, obtain the sieve or particle-distribution report, measurement method and material reference. Request an optical test separately if the intended evaluation requires a numerical whiteness criterion.
- Particle evidence
- Agree the method and fraction limits used for acceptance.
- Material reference
- Keep the physical report linked to the same grade as the chemical analysis.
Interpret activity within its method
Before comparing the 420ml designation, clarify the measured quantity, test conditions and endpoint. Obtain the full procedure and result rather than treating the activity wording as a verified reactivity ranking.
For either a steelmaking or chemical application, review current technical and safety documents and plan a representative assessment against the actual plant criteria. Keep the observations attached to the tested material. No general activity rate, numerical optical value or universal process outcome is established for selection here.
