Abstract

Experimental research on carbon ceramic composites fabricated from carbon and organoclay had been conducted. Electrical conductivity, specific wear rate, density and porosity, morphology, SEM EDX, and XRD were studied. The higher the content of carbon powder, the higher the electrical conductivity produced. Likewise, the higher the sintering temperature of composite increases the electrical conductivity of carbon ceramic composite. The higher the carbon powder content reduces the composite wear rate. Carbon content can increase the hardness of carbon ceramic composites. Composite density tends to be relatively stable with increasing sintering temperature. Increasing the content of carbon powder has shown to reduce composite density. The composite is getting lighter. The higher the carbon content in the composite increases the percentage of porosity of carbon ceramic composites, but it can still increase the electrical conductivity. Generally, carbon ceramic composites contain macroporous.
