Recording powder flow when evaluating tricalcium phosphate as an anticaking agent

Set up the comparison

Hold starting moisture, packaging and storage time constant for the blank and each candidate. Test powder flow through the same funnel or with the same established method.

Measurements to record

Calcium and phosphorus (% by mass). Label results as elemental or oxide equivalents and use a common reporting basis. Particle size distribution (µm or % sieve residue). State sieve opening and percentage passing. For fine or agglomerated material, specify dispersion and sieving procedures. Record the sample ID and method revision for repeat testing.

Interpreting the results

Record particle size alongside caking. Compare retained control and trial powders under the actual handling conditions.

What to record

• Particle size
• Humidity
• Sample packaging
• Flow test
• Caking
