Type: article
Abstract: This study characterizes the elemental composition of white teak wood powder impregnated with nano-silicon dioxide (nano-SiO2) and furfuryl alcohol (FA) using Scanning Electron Microscopy–Energy Dispersive X-ray Spectroscopy (SEM-EDS) data. A focused reanalysis compared untreated control powder with impregnated powder from white teak originating in Southeast Sulawesi, Indonesia. The impregnated sample was dominated by carbon (63.69 wt%) and oxygen (34.52 wt%), with silicon (1.54 wt%), potassium (0.11 wt%), and calcium (0.14 wt%) present as minor constituents. The corresponding atomic fractions were 70.50% C, 28.69% O, 0.73% Si, 0.04% K, and 0.05% Ca. Silicon and potassium were not detected in the control, which contained 63.76 wt% C, 36.13 wt% O, and 0.12 wt% Ca. The appearance of 1.54 wt% Si after treatment provides local evidence of a silicon-bearing deposit consistent with the incorporation of nano-SiO2 during impregnation. Nevertheless, EDS alone does not establish chemical phase identity, and results from a single analyzed area cannot be considered representative of the entire specimen. Replicated elemental mapping together with complementary XRD, FTIR, or XPS analyses are required to confirm the distribution and chemical form of the deposited silicon.
