The effects of freeze-silicone oil heat treatment (combination of treatments) on the chemical properties of wood were investigated using fourier transform infrared (FTIR), X-ray diffractometer (XRD) and thermogravimetric analysis (TGA). Results obtained showed that the impact of combine treatments on the wood was positive. FTIR results showed apparent changes in the chemical composition of the treated wood, XRD results indicated relative increase in the crystallinity index of the treated wood compared to the untreated and TGA showed reduction in the weight loss of the treated as compared with the untreated wood samples.
