Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Qualifier:
equivalent or similar to guideline

Key result
Melting / freezing pt.:
ca. 2 300 °C
Atm. press.:
ca. 1 013 hPa
Decomposition:
no
Sublimation:
no
Conclusions:
A melting point value of 2300°C is reported in a handbook which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable.
Executive summary:

The melting point of calcium carbide is reported by Budavari S. (cited in "The Merck Index - An Encyclopedia of Chemicals, Drugs, and Biologicals", 1996) to be 2300°C.

The data is reported in a handbook which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable.

Description of key information

A melting point value of 2300°C is reported in a handbook which has been subject to peer-review and in which the original data sources are traceable.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
2 300 °C

Additional information

The melting point of calcium carbide is reported by Budavari S. (cited in "The Merck Index - An Encyclopedia of Chemicals, Drugs, and Biologicals", 1996) to be 2300°C.

The data is reported in a handbook which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable.

The melting point is assumed to relate to a test material of a higher purity than commercial calcium carbide.
