Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Type of information:

Adequacy of study:

Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Remarks:
Handbook data are considered from a trusted source. Data have been taken from many sources, including both compilations and the primary literature - where conflicts were found, the value deemed most reliable was chosen. The reference was peer-reviewed. In addition, the reference sources are indicated although not leading to sufficient information on the material & method used.

Conclusions:
The CRC Handbook of Chemistry and Physics (80th ed.) mentions a density near room temperature of 2.11 g/cm3 for potassium nitrate.

Adequacy of study:
weight of evidence
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
documentation insufficient for assessment
Remarks:
The preface and introduction to this book (9th Edition) provide no indication that the physico-chemical data has been ‘peer reviewed’. The reference source is not indicated leading to insufficient information on the material & method used.

Conclusions:
Sax's Dangerous Properties of Industrial Materials (9th. ed.) mentions a density at 16°C of 2.11 g/cm3 for potassium nitrate.

Description of key information

Combining three handbooks, the relative density of potassium nitrate is 2.1.
