Three-dimensional Real-time Observation Device for the Growth of Melt Crustals

A three-dimensional optical in-situ observation method was newly developed. The transmission magic-mirror method was applied to visualize and record the whole process of growth and melting of transparent crystals taking place in high temperature up to 1000℃ For matching to three-dimensional observation, a set of special furnace and crucible was designed and the growing process can be observed in two perpendicular directions and recorded in situ by CCD camera simultaneously. By using this system, the process of KCl dendrite growth was observed.
