Key result
Relative self-ignition temperature:
197 °C
The self ignition temperature of VACODYM 687 is 197°C.
Executive summary:

The self ignition temperature of a representative sample alloy VACODYM 687 is 197°C.

Description of key information

Since the self-ignition temperature depends on the overall rare earth content and the particle size of the alloy, a representative alloy VD 687 was tested.

The self ignition temperature of the representative sample alloy VACODYM 687 is 197°C.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
197 °C
