“…Gốm cacbon thông thường được tổng hợp bằng cách nung kết khối cacbon vô định hình hoặc cacbon graphite ở nhiệt độ cao. Với thành phần chính là nguyên tố cacbon, gốm cacbon thường được ứng dụng làm vật liệu chịu nhiệt độ cao [2], vật liệu gia cường [3], vật liệu làm điện cực [4], vật liệu y sinh [5], … Trong các nghiên cứu trước đó, vật liệu gốm cacbon thường được nung kết khối ở nhiệt độ rất cao (trên 1500 o C) [6][7][8]. Nhiệt độ nung cao ảnh hưởng lớn đến khả năng sản xuất và gía thành của gốm cacbon.…”

In this study, carbon ceramics were fabricated from cashew nut shell waste and phenolic resin. The used phenolic resin in the research was also made from cashew nut shell waste by liquefied wood methods. The sintered degree of carbon ceramics was assessed through physical properties such as bending strength, porosity, and density. The functional groups, phases and microstructure of carbon ceramics were determined by the Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscope (SEM) methods. The results indicated that it was possible to sinter to form carbon ceramics at a low temperature (900oC). Carbon ceramics which were sintered at 900oC had a bending strength of 65.29 MPa, a porosity of 24.17%, and a density of 1.2 g/cm3. The results of phase composition analysis showed that the main phase component of carbon ceramics was amorphous carbon. In addition, phase also appeared the cristobalite mineral. The results of microstructure analysis showed that the carbon ceramics were sintered. However, pores still appeared in the ceramic structure.
