Slow forming crystals
WebbRecrystallization is a technique used to purify solid compounds. 1 Solids tend to be more soluble in hot liquids than in cold liquids. During recrystallization, an impure solid compound is dissolved in a hot liquid until the solution is saturated, and then the liquid is allowed to cool. 2 The compound should then form relatively pure crystals. Webb6 nov. 2012 · The most promising crystals for XRD are transparent and have sharp edges. Ideally, crystals are 0.2–0.4 mm in at least two of the three dimensions. There are no …
