In order to observe room temperature hydrated specimens in an electron microscope, the following conditions should be satisfied: The specimen should be surrounded by water vapor as close as possible to the equilibrium vapor pressure corresponding to the temperature of the specimen.The specimen grid should be inserted, focused and photo graphed in the shortest possible time in order to minimize dehydration.The full area of the specimen grid should be visible in order to minimize the number of changes of specimen required.There should be no pressure gradient across the grid so that specimens can be straddled across holes.Leakage of water vapor to the column should be minimized.

The equilibrium vapor pressure of magnesium over the reaction between the calcined dolomite and aluminum was measured by means of the transportation method. In the temperature range 886–1035 °C, the reaction was found to proceed according to the equilibrium[Formula: see text]and the measured equilibrium pressure of magnesium can be expressed by the equation[Formula: see text]
