- Executive summary:
The melting point of gadolinium zirconium oxide has been determined in a study according to OECD guideline 102. The melting point/melting range is determined by differential scanning calorimetry (DSC). The DSC measurement with a heating rate of 10 K/min showed no endothermal effect (melting) up to the final test temperature of 500 °C. Thus, it can be concluded that the test item had no melting point up to the final test temperature of 500 °C.
Reference
One DSC measurement with a heating rate of 10 K/min showed no endothermal effect (melting) up to the final test temperature of 500 °C. The results of the DSC measurements are summarized inTable1.

Key value for chemical safety assessment
Additional information
The melting point of gadolinium zorconium has been determined in a study accoring to OECD guideline 102. The melting point / melting range is determined by differential scanning calorimetry (DSC). The DSC measurement with a heating rate of 10 K/min showed no endothermal effect (melting) up to the final test temperature of 500 °C. Thus, it can be concluded that the test item had no melting point up to the final test temperature of 500 °C.
