摘要
Disclosed is a method for recrystallizing solid materials (e.g. RDX) from systems comprised of a solute, which is the eventual material recrystallized, a liquid which is a suitable solvent for the solute, and a gaseous component which is soluble within the solvent and whose presence therein causes the solvent to approach or attain a supersaturated state, thereby precipitating (recrystallizing) the solute material. By control of process parameters (pressure, temperature, time, and rate, rate of injection of gas, etc.) the operator can influence the properties of the material recrystallized.
