Copper Oxide (Chemical Formula: CuO) is a premium black copper oxide powder. It is slightly amphoteric and mildly hygroscopic. The product is thermally stable and decomposes to release oxygen at high temperatures. It is insoluble in water and ethanol but readily soluble in acids. Due to its outstanding physicochemical properties, it is extensively used in numerous industrial sectors, including rayon manufacturing, ceramic glazes and enamels, battery materials, petroleum desulfurizers, pesticides, hydrogen production, catalysts, and specialty glass.

Storage & Transportation Safety Guidelines
Storage Requirements: Must be stored in a cool, well-ventilated warehouse. Keep away from fire and heat sources. Strictly prohibited from mixed storage with reducing agents, alkali metals, and edible chemicals; must be stored separately. The storage area should be equipped with suitable materials to contain spills.
Transportation Regulations: Packaging must be intact and securely loaded at the time of shipment. Ensure containers do not leak, collapse, fall, or sustain damage during transport. Mixed transport with reducing agents, alkali metals, and edible chemicals is strictly prohibited. Protect from direct sunlight, rain, and high temperatures during transit. Vehicles must be thoroughly cleaned after transport is completed.
