N2 - A dense, bulk ceramic of Ti3SiC2 containing impurities of TiC and Ti5Si3 was fabricated by hot pressing elemental powders of Ti, Si, and C. X-ray diffractometry, scanning electron microscopy, and transmission electron microscopy were used to determine the crystalline phases and observe the microstructure of sintered compacts, respectively. Ti3SiC2 exhibits anisotropic grain growth and the size of exaggerated grain is ∼ 25 μm in length. The average coefficient of thermal expansion of Ti3SiC2 was measured to be 9.29 × 10-6 K-1 in the temperature range 25-1400°C.
