General description

Zinc oxide, dispersion (ZnO) is a multi-function metal oxide with unique physio-chemical properties, which includes high chemical stability, broad range absorption spectra and high electrochemical characteristics. It can also be categorized as a semiconductor due to its high energy band width and high thermal stability that make it potentially useful in electronics and optoelectronics applications.

Application

ZnO dispersions have piezo and pyroelectric properties that make it useful in the development of sensors, generators, and photo-catalysis. It has low toxicity and biocompatibility, which facilitate its applications in biomedicine.
