Propellant for the NASA Standard Initiator

Hafnium, a metal normally found in the same ore as zirconium, is difficult to separate and may act as an ignition suppressant by elevating the autoignition temperature. Literature records a commercial grade of zirconium hydride of 2 to 6 micron particle size containing 1.8% hydrogen and 2.5% hafnium with an ignition temperature of 270C.

Zirconium MOF buckles under dynamite pressure Research

'When we crush MOFs under pressure, the structure collapses and breaks some of the chemical bonds that hold the structure together. Breaking chemical bonds costs energy and a lot of it,' explains Suslick.
