The chapter also examines the effect of compaction pressure, time and temperature on sintering of rock salt. Natural rock salt samples were crushed and milled in a disc mill to obtain fine powders in an experiment. The hot stage microscope allowed observing the in-situ volumetric shrinkage to be determined during the sintering process by measuring the area of the sample's projection in an optical setup by a CCD camera. Images were collected at a rate of 40 frames per minute. After the application of high pressures, the obtained samples are translucent and show the formation of macroscopic crack. Powder compacts prepared by uniaxial pressing, at different maximum pressures, were annealed at a constant heating rate (10 K min-1) to different maximum temperatures. These experiments were performed in a conventional sintering furnace under ambient atmosphere.
