PROBLEM TO BE SOLVED: To provide a woody material processing composition which improves the flame retardancy etc., of woody materials such as wood, and prevents the occurrence of the efflorescence problem of the processed woody materials, a method for processing the woody materials using the composition, and the woody materials processed by the method. SOLUTION: The woody material processing composition is prepared by adding a silicic acid compound in an amount of 0.05-0.5 mol in terms of the number of silicon atoms into 1 L of an aqueous solution containing 1.2-3 mol/L of phosphoric acid or phosphate ions, 0.15-0.5 mol/L of alkaline earth metal ions, 0.04-0.4 mol/L of alkaline metal ions, and 1.0-2.0 mol/L of ammonium ions. The method for processing the woody materials includes a process for impregnating the composition. The woody materials are obtained by being processed by the method. COPYRIGHT: (C)2011,JPO&INPIT
