This paper addresses the crystal growth by using the evaporation of a saturated aqueous solution.
KH
2PO
4-type powder and distilled water were mixed in order to grow a crystal. We made a proto- type incubator device, instead of using commercial products, to investigate the crystal’s growth. A
‘⊥’ shaped ruler helped with the measurement of the change in the volume of the saturated aqueous solution in order to control the temperature and the humidity. The angle between the pyramidal faces (101) and the prismatic faces (100) of the grown KDP crystal was around 45
◦degree. The possible termination depended on the array of the negative H
2PO
−4groups or K
+ions in boundary.
We discussed the characteristics of the behavior of the crystal produced by using the home-built incubator.
