Kinetics of Crystallization in Supersaturation

Kinetics of Crystallization in Supersaturation

Crystallization kinetics in supersaturation is two dominant processes, nucleation kinetics and growth kinetics, occurring during crystallization from solution. Nucleation kinetics define the rate of formation of a stable nuclei. Growth kinetics define the rate at which a stable nuclei grows to a macroscopic crystal.

Other grades of stainless steel, such as 303 or 202 stainless steel, don’t provide the same benefits. For a crystallization reactor, you’re going to need a corrosion-resistant tank. That means you need 304 stainless steel, at the least. Our 306L stainless steels offer even more corrosion protection, but also come with a heftier price tag.
