Processing steps
Step Chronology Date Type Process Changes
#1 before layer formation 1993-01-01 thermal synthesis of the sulfide by the evacuated silica tube method at 1273 K for 24 hours from native elements
#2 before layer formation 1993-01-01 pressure production of a pellet from the synthesized sulfide powder
#3 before layer formation 1993-01-01 thermal melting the pellet in an arc furnance formation of a compact sample
#4 before layer formation 1993-01-01 thermal quenching the melt quickly on water cooled copper plate formation of a compact melt droplet
#5 before layer formation 1993-01-01 mechanical embedding the melt droplet into epoxy resin
#6 during layer formation 1993-01-01 mechanical polishing of the embedded sulfide melt droplet to obtain a smooth and flat surface
Comments
The processing steps 2-4 were conducted under argon atmosphere, because Mg-rich sulfides are easily attacked by atmospheric moisture.
