Investigation on the electrical conductivity of Al2O3-Ti ceramic composites using a pressureless sintering process

Mechanical and electrical properties of 3Y‐TZP/TiSi2 composites sintered at different temperatures

“…It indicates that the conductive network has been formed and the percolation threshold exists between 30 and 40 wt.% TiSi 2 . As TiSi 2 was added into the matrix, TiSi 2 tended to contact each other to form the conduction pathway related to the percolation of dispersed TiSi 2 phase 31 . Due to the conductive nature of TiSi 2 networks, the current can pass through, and electrical properties can change drastically.…”

“…As TiSi 2 was added into the matrix, TiSi 2 tended to contact each other to form the conduction pathway related to the percolation of dispersed TiSi 2 phase. 31 Due to the conductive nature of TiSi 2 networks, the current can pass through, and electrical properties can change drastically. According to percolation and Bruggeman's effective media theories, 32,33 Equation (2) was often used to describe the effects of phase composition on the resistivity of composites.…”

Preparation of Al3Ti-Al2O3/Al Inoculant and Its Inoculation Effect on Al-Cu-Mn Alloy

“…The rod-like second phases were alumina whiskers, and it can be found that there were craters on the surface of the alumina whiskers and the whisker length was obviously reduced. At high temperature (1600~1700 • C), Al 2 O 3 will decompose and release O atoms, the O atoms can easily combine with the Ti atoms in the melt to form TiO 2 or Al 2 TiO 5 [43][44][45]. However, no diffraction peaks corresponding to other phases were observed in the XRD pattern shown in Figure 1, probably because too few reaction products were generated to be detected.…”
