2019-2-1 · High thermal conductivity, low thermal expansion and low density are three important features in novel materials for high performance electronics, mobile appliions and aerospace. Spark plasma sintering was used to produce light metal–graphite composites with an excellent coination of …
High‐resolution transmission electron microscopy revealed two different SiC‐SiC boundaries, that is, amorphous and clean boundaries, in addition to a fully crystallized junction phase. A high thermal conductivity was attributed to a low lattice oxygen content and the presence of clean SiC‐SiC boundaries.
2018-6-17 · Keywords: Aluminium nitride, Sintering additives, Spark plasma sintering, Thermal conductivity Introduction Aluminium nitride (AlN) is considered to be a promising material for microelectronic packaging because of its high thermal conductivity (320 W m21 K21 for the pure single crystal and 30– 270 W m21 K21 for sintered polycrystalline), low
Graphene holds great potential in metal matrix composites for thermal management due to its excellent thermal properties. However, the graphene/metal composites possessing both high thermal conductivity (TC) and low coefficient of thermal expansion (CTE) have not yet been realized.
The microstructure, thermal conductivity and dielectric constant of SPS AlN samples are examined. Results show that SPS can fabrie samples with superior thermal properties. Addition of 1 wt.% CaF 2 was found to have expedited the sintering process and this yielded thermal conductivity of …

2011-1-1 · Every university student becomes familiar with the concept of thermal conductivity, a fundamental physical property of materials, through his or her textbooks. Initial work on high thermal conductivity was carried out in 1911 by Eucken, who discovered that diamond was a reasonably good conductor for heat at room temperature.
Spark plasma sintering was used as consolidation method to maintain the particle size. The thermoelectric performance of FeSb 2 is limited by its high thermal conductivity. In this work, the thermal conductivity was suppressed by nearly 80% compared to the bulk value by introducing grain boundary stering of phonons on the nanoscale.
