A defined median makes a natural heavy-carbonate enquiry more precise than a general fineness label. XM-NC103 is an industrial white calcium carbonate powder with 99% minimum purity, D50 at 1μm and 97% whiteness for technical material comparison.
Use the median with the complete distribution
Compare the explicit 1μm D50 with the required powder specification and request the full particle report. The median does not establish a maximum particle size, so confirm the measurement method and any additional particle limits relevant to the intended process.
Review the chemical and moisture criteria
CaCO3 content is 99%, with moisture at 0.3% and pH in the range 7.5–9.5. Request current analysis and the corresponding methods before using those values as acceptance criteria for the actual offered XM-NC103 grade.
- Optical requirement
- Confirm the method supporting the 97% whiteness value.
- Surface requirement
- Ask whether any treatment applies and obtain its specification if relevant.
Define the actual industrial process
Describe the material system and the properties that will decide acceptance before planning a trial. The carbonate name and measured raw-powder profile do not establish a particular end-use benefit or a universal processing response.
Include the model, accepted assay and particle requirements in the enquiry. A complete grade report and a relevant process trial give the natural heavy powder a clear evaluation path without an assumed treatment or performance guarantee.
