Reference

Endpoint:

melting point/freezing point

Remarks:

Handbook data

Type of information:

other: Handbook data

Adequacy of study:

key study

Study period:

Not reported - Literature data

Reliability:

1 (reliable without restriction)

Qualifier:

according to guideline

Guideline:

other: Thermo Gravics Analytics

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.
