Metallic Functional Powders (MFP) for Pyrotechnics and Civil explosives

Metallic Functional Powders (MFP) such as aluminium powders for pyrotechnics and explosives serve to sensitize the explosives. In general aluminium powders do not completely react in the initial detonation but in a second phase of the combustion as accelerator in the post heating phase. Once initiated, they are highly flammable.

Beside fine powders with a high specific surface of >20.000 cm²/g also coarse products with an average particle size up to 100 µm are used, mainly in display fireworks.

In some case an oxidant agent, mainly potassium perchlorate is added to the mixture with aluminium powders. The oxidizing agent creates the oxygen which is needed in the burning reaction.

Metallic Functional Powders (MFP) for Reaction partners

In the chemical raw materials industry metallic powders can be applied as reactants for several industrial applications. Copper functional powders can react as a catalyst, e.g. in the Rochow synthesis in the production of silicones. Another application is the use of copper powder as anti-seizing element in greases.
