Fabrication of high thermal conductivity silicon nitride ...
2020-12-1 · The fabrication of silicon nitride (Si 3 N 4) ceramics with a high thermal conductivity was investigated by pressureless sintering at 1800 °C for 4 h in a nitrogen atmosphere with MgO and Y 2 O 3 as sintering additives. The phase compositions, relative densities, microstructures, and thermal conductivities of the obtained Si 3 N 4 ceramics were investigated systemically.
