Preparation and isochronal sintering behaviour of molybdenum disulphide compound

Abstract

The low-dimensional solid 2H-MoS2 has been prepared by the high-temperature solid state reaction technique. Different techniques such as positron annihilation, X-ray diffraction, microhardness and scanning electron microscopy have been used to study the isochronal sintering behaviour of this compound from room temperature to 700 ° C. In the positron annihilation experiments, an anomaly was observed in the temperature region 400 to 500 ° C. The presence and reduction of stacking fault defects, changes in the void size, breaking-up of grains and transcrystalline fractures during sintering were also investigated.
