TīmeklisZinc flake coatings create what is known as cathodic protection: the less noble zinc 'sacrifices' itself in order to protect the underlying metal. Steel can be protected in this way. The coating thickness is often between 5 μm and 15 μm, with thicker layers also possible where there are special requirements.

TīmeklisThe first ultrasmall Zn-MOF-74 nanodots with the average size within 10 nm were successfully synthesized by manipulating the initial conditions with a diluted material system. It was found that the ultrasamll MOF nanodots had a highly selective interaction with Fe 3+ and showed a specific blue colorimetric change in aqueous solution.
