✦ Synopsis

Measurements of the real portion of the dielectric constant of coal-water slurries at 750MHz are reported. Slurries of 40-65wt% of either Illinois No. 6, Utah bituminous or Texas lignite coals over the temperature range 11-71 "C were studied. The dielectric constant was independent of coal type and particle size within experimental error. The measured values of dielectric constants agreed with those predicted by the Looyenga equation: E'= [ey3+q5(q'/3-&3)]3 where: c', the mean value of the dielectric constant; E;, the dielectric constant (3.8) of the dry coal; E;, the dielectric constant of water; 4, the volume fraction of coal.
