Hot New Products Fev80 - Cobalt Oxide Powder Black Co3O4 Powder – Huarui Detail:

Product Description

Co3O4 is black or gray-black powder. The bulk density is 0.5-1.5g/cm3, and the tap density is 2.0-3.0g/cm3. Cobalt tetroxide can be slowly dissolved in hot sulfuric acid, but insoluble in water, nitric acid and hydrochloric acid at room temperature. When heated to above 1200 ℃, it will decompose into cobalt oxide. When heated to 900°C in a hydrogen flame, it is reduced to metallic cobalt.

Cobalt oxide powder has the characteristics of small particle size, uniform distribution, large specific surface area, high surface activity, low loose density, less impurity content, spherical and high specific surface area, etc. It meets the requirements of electronic-grade powder materials, and can be widely used in electrical, chemical and alloy material fields.
