General description

The thermal decomposition of zinc stearate was studied.

Application

Zinc stearate was used as a reference compound to study the infrared spectra of a colloidal stearate-capped ZnO catalyst substrate for analysing gas adsorption on a colloidal stearate-capped zinc oxide (ZnO) surface. It was also used to prepare the sample suspension injection required for improving the therapeutic treatment for periodontitis.
