Gravimetric analysis is a method of quantitative chemical analysis in which a substance is converted into a stable compound of known composition, and the mass of this compound is then measured. This technique offers a high level of precision and is particularly useful in determining the concentration of materials within complex mixtures. The gravimetric determination of titanium dioxide typically involves a series of well-defined steps, which include precipitation, filtration, washing, drying, and weighing.

Group 2B carcinogen

With the rise of nanotechnology, research in recent years has also shown the dangers of titanium dioxide (TiO2) nanoparticles, and their genotoxicity, which refers to a chemical agent’s ability to harm or damage DNA in cells, thus potentially causing cancer. 

To put this all into context maybe we should go back to the beginning & Bluescope steel who make all of our lovely Australian colour bond iron roofs.

Dispersion in the polymer: optimum dispersion should produce a good distribution and separation of titanium dioxide particles in the formulation.
