Abstract

<p>In-site observation of the crystal growth of compound from supercooled melt were conducted using salicylic acid-acetamide solution with the aim to gain a basic understanding of solidification process related to a functional material processing. In the experiment, the crystal growth and its morphology were investigated by varying degree of supercooling and temperature gradient. Based on the experimental results, the growth mechanism of facet-shape compound crystal was discussed in relation to the temperature and concentration fields. It was found that the growth velocity in the axis crystal direction became smaller when temperature gradient was larger, and the velocity in the width direction was controlled by degree of supercooling because of the interfacial kinetics.</p>
