Description

<p>LiCl-KCl binary mixture consists of two phases between liquidus temperature and eutectic point temperature. Our objective is to detect 1) its solid-liquid phase change and 2) the volume fraction of the solid phase. We have measured its resistance, which comes from impedance measurement using alternating current, and referred to the reported LiCl-KCl phase diagram. As a result, 1) the conductance is capable of detecting liquidus temperature and eutectic point temperature, and 2) it has a linear relation with the volume fraction by measurement using the current of 10kHz~100kHz.</p>
