> 600 °C
Atm. press.:
ca. 1 013 hPa
Decomposition:
no
Sublimation:
no
Remarks on result:
other: No melting point up to 600 °C observed. Optical inspection showed that substance remained unchanged. No mass loss or any endo- or exothermic effects detected.

This study was conducted according to EU Method A.1 and OECD guideline 102 in aGLP like setting. No melting point was observed for the test items in differential scanning calorimetry experiments. The test item remained unchanged. Therefore melting points of test item >600°C.

Description of key information

No melting point up to 600°C was observed, the test item remained unchanged.Three studies according to EU Method A.1 and OECD guideline 102 are available for boron doped barium europium strontium silicate. No melting point was observed for the test items in differential scanning calorimetry experiments according to EU A.1 up to 600°C. The test items remained unchanged. Therefore melting points of boron doped barium europium strontium silicates are >600°C.

Key value for chemical safety assessment
