Abstract

This paper describes a novel technique to visualize, 'in situ,' the solid-liquid interface during directional solidification. It is based on the principle of 'Infrared Autoradiography.' This technique is in general applicable to infrared materials depending upon their infrared transmission range and availability of infrared detection/imaging system in that range. Preliminary results on the application of this technique to potassium chloride (KC1) are included. The technique will allow, for the first time, 'in situ' monitor and control of interface shape and thus, help grow better quality crystals. In addition to the improvement in the crystal quality, the technique will have wide range of fundamental and practical applications in solidification processes of advanced IR materials.
