APPLICATIONS

Powder Metallurgy

Results of many intermediate and final processing steps are controlled by or
related to skeletal density of the metal. In addition, the performance of many
sintered or cast metal structures may be predicted from the skeletal density of
the starting metal powder.

Refractory Materials (ASTM C604-02)

True density is a useful value for: classification, detecting differences in chemical
composition between supposedly similar samples, indicating
mineralogical phases or phase changes, calculating total porosity when the
bulk density is known, and for any other test method that requires this value
for the calculation of results.

Calcined Petroleum Coke (ASTM D2638-10)

The density of calcined petroleum coke directly influences the physical and
chemical properties of the manufactured carbon and graphite artifacts for
which it is used. Density, therefore, is a major quality specification of calcined
petroleum coke and is used as a control in coke calcination.

Soil (ASTM D5550-06)

The specific gravity of soils that contain extraneous matter (such as cement,
lime, etc.) or water-soluble material (such as salt) must be corrected because
of the precipitate that forms on the specimen after drying. If the precipitate
has a specific gravity less than the parent soil grains, the uncorrected test
result will be too low. If the precipitate has a higher specific gravity, then the
uncorrected test value will be too high.

Powder coatings (ASTM D5965-20)

Total solids content can be used to determine minimum coverage obtainable
with different coating blends. Mixtures of dry pigments can be monitored by
comparing measured density with theoretical density based upon composition
of the mixture.

Clear or Pigmented Coatings (ASTM D6093-97)

Dried film density can be used in the determination of Volatile Organic
Compound (VOC) content of clear and pigmented coatings. VOC is required
by government regulations.

Rigid Cellular Plastics (ASTM D6226-10)

Plastic foams exhibit different properties based upon the ratio of open and
closed cells. Insulation foams limit thermal conductivity through pockets of
trapped gases contained within closed pores. Flotation devices owe buoyancy
to closed air-filled pores that prohibit water entry.

Pharmaceuticals (USP 699)

Composition of active and excipient ingredients can be monitored and
controlled through determination of product density. Polymorphic, hydrated,
and amorphous forms of products, as well as purity, can be determined by
comparing measured density with theoretical and historical values.
