Abstract: An aqueous wood preservation composition containing inorganic polymers of one or more of the following metals is disclosed; aluminum (approximately 3.8%-7.0% as Al203), zirconium (approximately 5.25%-9.1% as ZrO2), copper (approximately 0.7%-8.8% as CuO) and a fixing agent such as acetic acid or sodium acetate. The pH is adjusted to be between 2.0-4.0 using an inorganic base such as copper carbonate. The invention includes wood and cellulose fibers treated by the composition of the present invention as well as methods of preserving wood and cellulose fibers using the compositions.
