A useful aluminum-sulfate enquiry should state which grade records and sample measurements the purchasing decision needs. This industrial material is described as Al2O12S3 white granules, with Al2O3 content of 16% minimum and papermaking or mordant use directions.
Identify the grade on the current analytical record
Ask for confirmation of the actual offered material and hydrate state. Compare current Al2O3 analysis and required individual impurities with the accepted chemical limits, remembering that the 16% minimum refers to Al2O3 content rather than compound purity.
Define what the actual granule sample must satisfy
List the particle or other physical measurements needed by the project and request the associated methods. White-granule appearance does not provide those results, so sample acceptance should rely on actual measurements linked to the grade being considered.
- Report linkage
- Actual grade identity, current analysis and the sample reference for each required measurement.
- Trial linkage
- The intended papermaking or mordant duty and qualification results compared with accepted criteria.
Keep physical descriptors within the material comparison
Density is stated in literature terms as 2.71g/mL at 25°C, with the measurement scope to confirm. It does not specify bulk density, a process addition rate or an operating instruction, and relevant use acceptance still needs an actual trial.
Request current safety and technical information with the missing grade and sample questions clearly identified. Keep the analytical record and relevant process qualification together, without assigning a particular water-treatment use or approval from the general aluminum-sulfate identity.
