High-purity nickel sulfate: exists in anhydrous, hexahydrate, and heptahydrate forms. Commercial products are mostly hexahydrate, with two variants: α-type and β-type. The former is a blue tetragonal crystal, while the latter is a green monoclinic crystal.

Unlike electroless nickel plating and chemical nickel plating, electroless nickel plating deposits a nickel layer through chemical methods, while chemical nickel plating deposits a nickel layer through an external power source.
There are three main reasons for the widespread application of nickel-based superalloys. First, nickel-based alloys can dissolve more alloying elements and maintain a stable structure. Second, compared with iron-based and cobalt-based superalloys, nickel-based alloys can form a coherent ordered A3B type intermetallic compound γ[Ni3(Al,Ti)] phase, which can effectively enhance the strength of the alloy and make it more efficient. High temperature strength. Similarly, nickel-based alloys contain chromium, which gives them better oxidation and gas corrosion resistance than iron-based superalloys.
The core applications of nickel-based alloys can be summarized as: providing excellent mechanical properties and chemical stability in high-temperature, corrosive environments and precision industries.
