Zinc Oxide

Description

Zinc oxide is white at regular temperatures and yellow when heated. It can be prepared in a broad range of particle sizes, from macro conglomerates of several tens of microns, to colloidal dimensions, up to ultra-microscopic nano sized particles. It is most often marketed in the form of a very fine powder.
 
Zinc oxide has been produced commercially for well over a century. It was initially used as a pigment, and in the field of medicine. It is considered to be the most important zinc compound in industrial applications and in research.
Additionally, it serves as a raw material in the preparations of other zinc containing compounds.
 
Zinc oxide is produced either by the direct (American) process or by the indirect (French) process.
 
Numinor represents GH Chemicals of Canada.  GH Chemicals is a top quality producer of Zinc Oxides with GMP, USP, and FCC approved grades, These grades of zinc oxide offer the lowest levels of impurities in the market along with the strictest of quality control and certification.
