Spinodal Decomposition

Almost everyone has used spinodal decomposition: Dissolve powdered Jell-O (thank you again, Kraft Foods) in hot water to make a liquid. Let it cool and it segregates into a weak – but solid – network of gelatin with the water, flavor, and color trapped inside the gelatin network. The wordspinodalcom...

Summary:Almost everyone has used spinodal decomposition: Dissolve powdered Jell-O (thank you again, Kraft Foods) in hot water to make a liquid. Let it cool and it segregates into a weak – but solid – network of gelatin with the water, flavor, and color trapped inside the gelatin network. The wordspinodalcomes from a line with a curved bump or hump, a “spine,” on a temperature versus composition graph. Underneath the curved line, a material of mixed composition can separate into regions of different composition. (The decomposition could have been calledbumpodalorhumpodal, butspinodalsounded classier.) Although spinodal
