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.

Metallic Functional Powders (MFP) for Titanium dioxide

Aluminium paste is used in the bleaching stage in the production of TiO², especially in the “sulphate process”. Aluminium is also needed in the “chloride process” but with coarser products.

Ilmenite is titanium iron ore. Under high temperatures Ilmenite reacts with aluminium in an exothermal reaction, producing pure Ti and Fe and Al²O³ particles.  At the end of the reaction this results in pure white TiO². This is very important because TiO² is the most important white pigment used in many industrial applications such as paints, plastics, printing inks, in the paper industry. TiO² mainly improve opacity in these applications.

The amount of aluminium in the reaction is more than needed. This results  in a reaction of Al with Fe to form Fe²Al5.

AVL developed a special range of non-hazardous pastes for the titanium market which meet specific requirements.
