Abstract
Abstract LaMgAl 11 O 19 –Yb 3 Al 5 O 12 ceramic composites were prepared by pressureless sintering process at 1700 °C for 10 h in air. The microstructure and thermophysical properties of the composites were characterized by X-ray diffraction, scanning electron microscopy, high-temperature dilatometer and laser flash diffusivity measurements. LaMgAl 11 O 19 –Yb 3 Al 5 O 12 ceramic composites are composed of magnetoplumbite and garnet structures. LaMgAl 11 O 19 –Yb 3 Al 5 O 12 ceramic composites exhibit typical linear increase in thermal expansion with the increase of temperature. The measured thermal diffusivity gradually decreases with increasing temperature. Thermal conductivity of LaMgAl 11 O 19 –Yb 3 Al 5 O 12 ceramic composites is in the range of 2.6–3.9 W·m −1 ·K −1 from room temperature to 1200 °C.
