The particle density of a particulate solid or powder, is the density of the particles that make up the powder, in contrast to the bulk density, which measures the average density of a large volume of the powder in a specific medium (usually air).Sometimes it also refers as True density which contrasts with particle density as of internal porosity.The particle density is a relatively well-defined quantity, as it is not dependent on the degree of compaction of the solid, whereas the bulk density has different values depending on whether it is measured in the freely settled or compacted state (tap density). However, a variety of definitions of particle density are available, which differ in terms of whether pores are included in the particle volume, and whether voids are included.

- Kompaktdensitet är ett densitetsmått som används för porösa material. I kompaktdensiteten inräknas endast det kompakta materialets volym. Volymen för materialets öppna och slutna porer räknas inte med. Detta medför att kompaktdensiteten blir högre än skrymdensiteten. För ämnen som inte är porösa är kompakt- och skrymdensitet lika stora. (sv)

| - Die Reindichte, auch Skelettdichte, absolute oder wahre Dichte genannt, bezeichnet die Dichte des stofflichen Teils eines Körpers beliebigen Aggregatzustandes, d. h. ohne das Volumen evtl. enthaltener Hohlräume zu berücksichtigen:
* Bei porösen Festkörpern wird die Reindichte bestimmt, indem das Material solange zerkleinert und gemahlen wird, bis seine Teilchen keine Poren mehr enthalten (vgl. auch Stampfdichte). Das Gegenstück zur Reindichte poröser Körper ist die Rohdichte, in deren Bestimmung das Porenvolumen sehr wohl eingeht. Als gute Näherung zur Bestimmung der wahren Dichte werden Gaspyknometer mit Helium als Prüfgas eingesetzt.
* Bei Haufwerken ergibt sich die Reindichte bei der Kornanalyse aus Wiegen und Hochrechnung. Das Gegenstück zur Reindichte von Haufwerken ist die Schüttdichte.
* Die Reindichte von Flüssigkeiten oder Gasen ist die Dichte des Hauptstoffes ohne gelöste Anteile, Schwebstoffe, Luftblasen o. Ä. Messung erfolgt durch Ruhenlassen der Probe, Sedimentation und Entgasung sowie Fällungsreaktionen. (de)
