Wood-inorganic material composite (WIC) was prepared by impregnating wood with copper sulfate (CuSO4․5H2O) solution and by immersed wood in sodium carbonate(Na2CO3) solution in order to introduce insoluble copper compounds {copper carbonate hydroxide, CuCO3 ․Cu(OH)2} into the wood to give fungicidal effects in treated-wood. The weight percent gains (WPGs) of treated wood reached maximum value by impregnation of 20% copper sulfate solution and immersion in about 15% sodium carbonate solution for 24 hrs. Inorganic substances were present mainly in the lumina and cross-field pitting of tracheides. These substances were proved to be the insoluble copper carbonate hydroxide against water by the energy dispersive X-ray analyzer in conjunction with a scanning electron microscope (SEM-EDXA). The treated specimens showed high preservative effectiveness because the weight losses were hardly occurred by the fungi degradation test.
