The substance is then burned to produce platinum sponge.
2.
It can also be prepared by the reaction of oxygen difluoride with platinum sponge.
3.
When a valve is opened, a jet of hydrogen is released onto a platinum sponge.
4.
Dioxygenyl hexafluoroplatinate can be synthesized from the elements by the action of a mixture of oxygen and fluorine gas on platinum sponge at 450�C.
5.
The hydrogen is led over a platinum sponge catalyst, where it reacts with air oxygen, heats the catalyst and ignites from it, producing a gentle flame.
