Abstract

The study is about the fabrication of kaolin-carbon ceramic composites, by controlling the size of carbon particles, with the mesh size of 150; 200; 250. Kaolin-carbon ceramic composite is fabricated with a composition ratio of 50:50; 60:40; and 70:30% weight, sintering pyrolysis at 950 °C, rate 2 °C/min, compaction 200 bar. The physical properties of the density/porosity, the conductivity properties of electric currents and voltages, the properties of electrical conductivity, elements and microstructures have been investigated. The smaller the size of the carbon particles, the lower the density. The higher the kaolin content the higher the composite density. At a composition ratio of 50:50 %wt, the size of the mesh carbon particle 150, at a voltage value of 4 volts, conducts an electric current of 0.89 [Ampere], and exhibits an electrical conductivity of 17 [S/m].
