Novel paper‐derived Ti3SiC2‐based ceramics are fabricated by spark plasma sintering (SPS). A Ti3SiC2‐loaded preceramic article is used as feedstock. The sintering temperature and pressure are 1100–1200 °C and 20–50 MPa, respectively. The influence of sintering parameters on phase composition and microstructure is analyzed by X‐ray diffraction (XRD) and scanning electron microscopy, respectively. In addition, energy‐dispersive X‐ray spectroscopy is conducted to analyze the distribution of elements and the phase arrangement depending on the sintering temperature. XRD analysis of the composites sintered at 1100 and 1200 °C shows the presence of Ti3SiC2, TiC, and TiSi2 phases while the content of Ti3SiC2 phase decreases with increasing temperature. It is shown that an increase in both temperature and pressure lead to higher densification of the composites. Elongated pores are observed in the composites, which are formed as a result of cellulose fiber decomposition during the sintering process. The maximal value of the flexural strength of 300 MPa is measured for the composite with the highest density. The influence of SPS parameters on the formation of phase composition, microstructure, and mechanical properties of the paper‐derived Ti3SiC2‐based ceramics is discussed.

火花等离子体烧结制备纸基Ti3SiC2基材料
新型纸衍生的Ti 3 SiC 2基陶瓷是通过火花等离子体烧结（SPS）制成的。负载有Ti 3 SiC 2的预陶瓷制品用作原料。烧结温度和压力分别为1100–1200°C和20–50 MPa。分别通过X射线衍射（XRD）和扫描电子显微镜分析了烧结参数对相组成和微观结构的影响。此外，还进行了能量色散X射线光谱分析，以根据烧结温度分析元素的分布和相的排列。在1100和1200°C烧结的复合材料的XRD分析表明存在Ti 3 SiC 2，TiC和TiSi 2Ti 3 SiC 2相的含量随温度升高而降低。结果表明，温度和压力的增加导致复合材料的致密化程度更高。在复合材料中观察到细长的孔，这些孔是由于在烧结过程中纤维素纤维分解而形成的。对于密度最高的复合材料，测得的弯曲强度最大值为300 MPa。讨论了SPS参数对纸质Ti 3 SiC 2基陶瓷的相组成，微观结构和力学性能的影响。
