What is nickel oxide powder? Nickel oxide powderis insoluble in water and liquid ammonia. It is soluble in sulfuric acid, nitric acid, hydrochloric acid, and ammonia. It is oxidized to nickel trioxide when heated to 400 ℃ in the air. At 600 ℃, it is restored to nickel oxide. The nickel oxide calcined at low temperatures has chemical activity. The activity is small if the nickel oxide calcined at 1000 ℃ is green. And with the increase of preparation temperature, the density and resistance of nickel oxide increase, and Solubility and catalytic activity are reduced. Nickel oxide is a sealant for enamel and a pigment for ceramics and glass. It is also used in magnetic materials, metallurgy, and picture tube industries and is also a raw material for manufacturing nickel salts and nickel catalysts.
Preparation of nickel oxide powder The agglomeration phenomenon is common in the nanopowder prepared by the traditional aqueous liquid phase method, which indicates that these processes have certain defects. The alcohol solvent method can eliminate the agglomeration phenomenon of the traditional aqueous liquid phase method. In the wet preparation of nano nickel oxide, aggregates may occur at each stage. The main source of aggregation is the presence of non-bridging hydroxyl groups on the surface of the precipitated particles; The second is the capillary contraction effect of precipitated particles during Dehydration and drying. In the alcohol solvent method, alcohol is used to avoid the formation of non-bridging hydroxyl groups and the capillary contraction effect during Dehydration and drying. At the same time, because there are physical and chemical adsorbed alcohols in the precursor particles, which can further prevent the particles from approaching, the formation of agglomeration is effectively prevented. In the heating process, the physically adsorbed alcohols are removed first, and with the increase of temperature, Dehydration and transfer chemisorption of alcohol occur. Finally, CO is released to obtain NiO powder.
Use of nickel oxide powder It is an adhesive, colorant for enamel, and pigment for ceramics and glass. It is used in the production of Ni-Zn ferrite, etc., in the production of magnetic materials, as a raw material for the production of nickel salts, as well as a nickel catalyst, and is used in metallurgy and picture tubes.
Price of nickel oxide powder Nickel oxide powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of nickel oxide powder. A large amount of large amount will be lower. The price of nickel oxide powder can be found on our company's official website.
