摘要
Machinable SiC ceramics are prepared with the addition of Al2TiO5. Ready-to-press SiC and Al2TiO5 powders are mixed and pressureless sintered at 1750 degrees C and 1850 degrees C for 1 h. The weight ratios of the SiC and Al2TiO5 powders are 100 : 0, 100: 10, and 100 : 20. After sintering, only SiC peaks are detected in the X-ray diffraction analyses. The density, strength, and grain size of the SiC increase with increases in the Al2TiO5 content and sintering temperature. The Al2TiO5-doped specimens are easy to micro-hole machine Based on the density and strength data, the ceramics sintered at 1850 degrees C can be used as machinable ceramics.
