Technical aluminium flakes, aluminium powders,aluminium paste, foil grit, spray grit
The chemical properties of metals are used in many ways in technical chemical applications. Metal powders are used either as chemical reaction partners (“reactant”), energy sources or catalysts. Both “flakes” of metal powder are used as well as spray grit made of aluminium, copper and copper alloys. Selection depends on the application and, in most cases, is made per customer.
In pyrotechnics, lamellar aluminium powders and flakes are used in addition to other fuels and effect makers in firecrackers and small rockets (sound effects), in fireworks (propellant and light effects), for stage effects, in sparklers and in other pyrotechnical products.
Titanium dioxide is the most important white pigment worldwide. The annual demand is 4 to 5 million tons per year. About half is used in the pigment industry and the rest in coloring plastics, in printing inks and in the paper industry.
