Woodceramics is carbon ceramics with porous structures that can be used in many technical fields. In this study, woodceramics was prepared by mixing cashew nut shell waste (CNSW) and liquefied wood with a ratio of 1/0.6 and then sintered in an inert atmosphere at 700 oC-1200 oC. The influence of sintering temperature on the carbonization behavior of formed woodceramics was determined by X-ray diffraction, Fourier transforms infrared spectroscopy, Isotope Ratio Mass Spectrometry measurement, and Scanning Electron Microscope/ Energy Dispersive X-Ray Analysis techniques. The experimental results showed that the carbon content increased when the sintering temperature increased. In addition to the increased carbon content, the degree of graphitization of woodceramics also increased. It is represented by an increased intensity of the (002) peaks and a decrease in the d002 value on the X-ray diffraction patterns. The SEM/EDX results also showed that appeared small graphite particles in the amorphous background at 1000 oC-1200 oC. However, the d002 value of the samples is only in the range of 0.3339-0.4094 nm, so the structure of the formed carbon is a non-graphite structure
