Principles of method if other than guideline:
Thermogravimetric analysis (TGA): mass change versus temperature or time.
Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. This measurement provides information about physical phenomena, such as phase transitions, absorption and desorption; as well as chemical phenomena including chemisorptions, thermal decomposition, and solid-gas reactions
GLP compliance:
no
Type of method:
thermal analysis
Key result
Melting / freezing pt.:
> 400 °C
Decomposition:
yes
Decomp. temp.:
> 400 °C
Remarks on result:
other: Literature data
Conclusions:
Following the thermal gravimetric analysis as reported in the literature (Miller, 1957), there is no melting temperature at 375°C for zirconium hydride and the material starts to decompose at > 400°C.
