Dissolution and Crystallization of Table Salt (NaCl)
| With the cooling Peltier stage, water vapor pressure in the specimen
chamber can reach the dew point (100% humidity) and water will condense
on the stage. Salt crystals were placed on the stage at +5°C. Pressure
in the chamber was gradually increased and crystals were dissolved in condensed
water (first four pictures below ) until there was nothing left but water
solution of NaCl (picture in the center). Pressure then was decreased,
and salt crystallized (last four pictures). x 250. |
Resolution in Wet Mode is practically the same as in high vacuum
mode
x 100,000. Vaporized gold. Chamber
