Wholesale Factory Price Nickel (II) Oxide Green Powder Special for Coloring
Basic information:
Nickel oxide is a green powder, yellow powder when overheated, specific gravity 6.6-6.8, melting point 1990ºC. It is oxidized to nickel sesquioxide by heat to 400ºC in the air, and at 600ºC, it is reduced to nickel monoxide and calcined at low temperature to obtain nickel monoxide, which has chemical activity. If the nickel oxide obtained by calcination at 1000ºC is greenish-yellow, the activity is small. The solubility and catalytic activity decreased with the increase of the preparation temperature and the increase of the density and resistance of nickel oxide.
Color: Nickel oxide can appear in different colors, including green, blue-green, etc., which makes it an important colorant.
Stability: tinting special nickel oxide needs to have good chemical stability to ensure its stability and reliability in the tinting process.
