- Principles of method if other than guideline:
- The true density of the sample was determined using a helium stereopycnometer. The technique is based on the determination of the true volume that the powder occupies by means of the difference between the cell volume and the volume that the helium occupies that is introduced to complete the cell filling. True density is calculated taking into account the mass of the powder used. The cell used for the density determination was the so-called Large cell, with a volume of 135 cm³.
The sample was dried in a laboratory oven at a temperature of 110 °C for at least two hours and then placed in a desiccator, before testing, to reach room temperature.
Before proceeding with the sample density measurement, the proper functioning of the instrument was verified using micronized zirconium oxide as standard, which allows measurement traceability to be assured. - GLP compliance:
