Microwave Sintering of High Thermal Conductivity Aln

In this study, a combustion synthesized AlN powder was sintered using microwave as heating source. The microwave was 2.45 GHz and the sintering process was carried out in a single-mode cavity. The sintering temperature was between 1800°C and 2000°C with a power ranging from 400 to 700W. The as-synthesized AlN was ground to under 2μm and yttria was used as sintering aid. The effects of the amoun...

Effects of AlN Coating Layer on High Temperature Characteristics of Langasite SAW Sensors

High temperature characteristics of langasite surface acoustic wave (SAW) devices coated with an AlN thin film have been investigated in this work. The AlN films were deposited on the prepared SAW devices by mid-frequency magnetron sputtering. The SAW devices coated with AlN films were measured from room temperature to 600 °C. The results show that the SAW devices can work up to 600 °C. The AlN...

Development of AlN/Epoxy Composites with Enhanced Thermal Conductivity

AlN/epoxy composites with high thermal conductivity were successfully prepared by infiltrating epoxy into AlN porous ceramics which were fabricated by gelcasting of foaming method. The microstructure, mechanical, and thermal properties of the resulting composites were investigated. The compressive strengths of the AlN/epoxy composites were enhanced compared with the pure epoxy. The AlN/epoxy co...
