摘要
Electric current-assisted technologies stand as a promising route to reduce the carbon footprint of the 21st century industry. Nevertheless, recent activities on flash sintering have shown that electrically-induced DC Joule heating in silicate glasses is highly inhomogeneous under the effect of a direct electric field, thus limiting further developments and industrial applications. In this work, we have shown that the Joule heating in soda lime silicate glass can be tailored and controlled by changing the material used as electrode. The highly inhomogeneous temperature profile developed using platinum electrodes turns into a well-homogenous distribution by employing molten NaNO3 electrodes.
