Peritectic alloy-like analogue directional solidification crystallizer suitable for working under function of current

The invention provides a peritectic alloy-like analogue directional solidification crystallizer suitable for working under the function of current and belongs to an experimental apparatus for peritectic alloy-like analogue directional solidification under the function of current. A melting-zone hot-end red copper heat-transfer plate and a melting-zone cold-end red copper heat-transfer plate are connected through glass sheets which are bonded with silica gel, so that the leak tightness of a melting zone is guaranteed to facilitate the formation of a stable temperature gradient GT at two ends of the melting zone, and the lateral heat dissipation is avoided. Besides, compared with the crystallizers manufactured by mechanical connection in the prior art, the crystallizer can control the temperature gradient in the directional solidification process more accurately, and provides the support for the experiment and real-time observation on directional solidification of high-melting point peritectic alloy-like analogues under the function of current.
