CHEMICAL INDUSTRY GRADE ZINC OXIDE

NANO-ZINC OXIDE FOR DESULFURIZER

Nano Zinc oxide for Desulfurizer
   Zinc oxide is emerging in recent years a new type of high performance inorganic materials. As a result of the reduced size and increased surface area, in the Zinc oxide surface to produce a large number of surface defects and oxygen vacancies, making Zinc oxide sulfur capacity of the room temperature is much higher than zinc oxide.
