Title:
CRYSTALLIZATION METHOD, CRYSTALLIZATION APPARATUS, AND MICRO-CRYSTAL
Document Type and Number:
Japanese Patent JP2009131737
Kind Code:
A
Abstract:
To develop a technology for crystallizing crystal, even with a dilute solution with the concentration of a solute below solubility.
A crystallization method is disclosed in which a compound that is a solute dissolved in the solution, or a compound obtained by reacting the solute is precipitated and crystallized. In the course of introducing bubbles into the solution, gas forming the bubbles being dissolved in the solution to contract the bubbles, the compound is coagulated and precipitated on the bubble surfaces, and density is increased to thereby crystallize the compound.
