Is nickel oxide harmful to human body?

What is Nickel oxide powder?
Nickel oxide is a p-type semiconductor material with a band gap of 3.7eV. It is often used as a photocatalyst and cathode material of nickel-iron batteries in traditional industries. Nickel oxide is used as a pigment for ceramics and glass. The enamel industry is used as a dense Chemicalbook binder and colorant for enamel. The ceramic industry is used as the raw material of pigment. Used as the raw material of nickel-zinc ferrite in the production of magnetic materials. The glass industry is used as a colorant for brown glass and CRT glass shells and also as a raw material for manufacturing nickel salts and nickel catalysts.
Density: 6.67g/cm3
Melting point: 1960
Appearance: olive green crystalline powder
Solubility: insoluble in water
preparation method of Nickel oxide powder
A method for preparing nickel oxide nanocrystals comprises the following steps: firstly, preparing 170mL of NiCl2 deionized water solution with a molar concentration of 0.12mol/L; Then, 77.5mL of water/ethanol solution of KOH with a molar concentration of 0.4mol/L was added dropwise to the solution, stirred for 5min, and then centrifugally purified. The obtained green precipitated Chemicalbook was dispersed in 200mL of a mixed solution of ethanol and dimethyl sulfoxide (the volume ratio of ethanol to dimethyl sulfoxide was 1:1), and reacted at 150 for 3h, and then centrifugally purified to obtain nickel oxide nanocrystals. Uniformly dispersing nickel oxide nanocrystals in anhydrous ethanol to obtain ethanol dispersion of nickel oxide nanocrystals (NiOx).
toxicity of Nickel oxide powder
Nickel can enter cells, causing the destruction of enzymes and metabolic processes in cells, which may lead to the formation of some carcinogens. Contact with nickel salt can cause nickel eczema and nickel scabies. Maximum allowable concentration in the air: bivalent nickel oxide is 0.5mg/m3 (calculated as nickel). Operators should wear gas masks and gas masks during production, and direct skin contact should be prevented to the greatest extent. Try to implement a mechanized operation to avoid dust. People who are exposed to nickel compounds at work should have regular physical examinations.
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.
