Additional information
The melting point of Ditantalum pentaoxide was reported to be 1875 ºC according to the CRC Handbook of Chemistry and Physics 92nd Edition (2011 -2012). The handbook has been assigned a reliability score of 2 using the principles for assessing data quality as set out in Klimisch (1997).
Three additional handbooks have been used as supporting studies for this endpoint. Kirk (1997), Lide (2010) and Clayton (1981) have recorded the melting point of Ditantalum pentaoxide in peer reviewed handbook and the data has been cited as found in the literature. The values provide sufficient consistency to act as supporting studies.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
