Abstract
Anthracite has been calcined under controlled conditions. Weight loss, impurity content, pore volume, specific density, mean crystallite height, interlayer spacing and specific electrical resistivity have been measured at varying heating rates, temperatures and holding times. A model has been developed which expresses the electrical conductivity as a function of temperature and holding time. The model is used to estimate the mean electrical conductivity of calcined anthracite when the temperature gradient in the electrical calciner is assumed to be linear.
