摘要

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.
