When looking for information on the melting point of potassium chloride, it is important to understand the properties of the molecule. Potassium chloride is a type of alkali metal, formed from the bonding of a Potassium atom with a Chlorine atom. It is used in a wide variety of scientific, medical, and industrial applications.
In solid state, potassium chloride has a B1 face-centered cubic structure. This structure is highly refractory at moderate pressures. Therefore, KCl is an excellent candidate for sample containment and calibration at high temperatures.
However, the melting curve of KCl at moderate pressures has not yet been validated. In order to do so, more data at lower pressures are needed. The first step in this process is to obtain an accurate measurement of the melting point at a given pressure.
This is done by obtaining a reference melting curve. Assuming the melting curve is accurate, the current-temperature relation can be used to locate the melting point. For example, if the ionic current of KCl is found to rise steeply with temperature, the point of highest current can be determined.
Several studies have investigated the influence of temperature on the ionic conduction of KCl. These results have yielded an ionic current that ranges from less than 50 mA at a low temperature to 400 mA at a high temperature.
A better design of the ionic conduction experiment is required to improve the accuracy of this measurement. Reproducibility of the measurements is achieved by identifying the steps of the press load and the resolution of the pressure transducer.
