Calcined Method Zinc Oxide
Appearance: Slightly yellow or white powder
Calcined method Zinc Oxide is divided industry grade and feed grade. Industry Grade Zinc Oxide has merits as follows: Impurity content is lower, specific surface area and stacking density (bulk) is large. It is used in ceramics, rubber industry etc.
Its standards of content have 99.5%, 99%, 98%. Feed grade Zinc Oxide's content higher and its content of lead, cadmium, arsenic are lower. Feed Grade Zinc Oxide's content has 99% and 98%.
