Conclusions:
Titanium hydride melting point is >400°C. At 450°C, TiH2 starts to decomposes before melting.

Description of key information

Titanium hydride decomposes before melting (400°C). Handbook data report a melting point between 400 and 450°C and are mentioning that the material decomposes before melting.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
400 °C
