gray-black powder. Soluble in hot hydrochloric acid release chlorine, soluble in hot sulfuric acid or nitric acid release oxygen, that is slightly soluble in cold acid, insoluble in water. About 600 deg C decomposition of nickel oxide and oxygen.
nickel carbonate calcination method: first, the metal nickel is made into nickel sulfate solution, and then the double decomposition reaction is carried out with sodium carbonate. The product is filtered to remove sodium sulfate, then concentrated, cooled and crystallized, centrifuged and dried, the obtained dried nickel carbonate was calcined and pulverized by ball milling to obtain nickel oxide.
It is used as a generating agent for oxygen, a material for electronic components, a material for storage batteries, and nickel.
packed in an iron drum lined with a polyethylene plastic bag with a net weight of 40kg per drum. Store in ventilated, dry warehouse. The container shall be sealed, protected from moisture and heat. It cannot be stored and mixed with strong acid and strong base. Toxicity and protection: see nickel oxide.
