In situ observation of temperature dependence of concentration field during growth of KB5 crystals by holographic interferometry
Abstract
The growth of potassium pentaborate tetrahydrate crystals was studied by both gel and low temperature solution methods for simulation of crystal growth in space. A set of in situ experiments concerning the temperature dependence of KB5 crystal growth were carried out by holographic interferometry. The experimental results showed that the concentration distribution during cooling is quite different than that in heating, and that, the influence of temperature on the concentration of KB5 in a free solution is more sensitive than that in the gelled medium. The findings will benefit the design of the facility which could be used for crystal growth in space and on the Earth.
