Titanium dioxide industry

Titanium dioxide is the most important white pigment. 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.

In the manufacturing process, following the “sulfate process”, large amounts of lamellar aluminium powders and pastes are used in the “bleaching stage”. Aluminium is also needed in the “chloride process”, but in this case in considerably coarser particle sizes.

Aquapor

The Aquapor® series includes dust-free aluminium paste preparations consisting of aluminium powder, water and stabilizing additives.

These pastes in a soluble matrix are characterized by excellent dispersion and, at the same time, a high degree of stability in the paste suspension.
