Abstract
The dielectric constant is an important characteristic of limestone. It is significant in engineering applications and in the interpretation and recognition of remote sensing data. Therefore, it is important to understand how the dielectric constant of limestone varies with temperature. In this study, the dielectric constants of limestone samples were measured during heating to 25 °C, 100 °C, 200 °C, 300 °C, and 400 °C in a furnace. The results show that the dielectric constant of limestone decreases with temperature increase, with the decrease becoming more rapid over 300 °C.
