Abstract

An investigation of engineered composites of kaolin and synthetic carbon has been conducted. The composite was developed from local kaolin materials from Singkawang, West Kalimantan, Indonesia, and synthetic carbon from organic coconut coir waste. The study is intended to determine the electrical conductivity properties of these engineering materials. Density values due to the increase in sintering temperature are relatively the same and stable at adjacent values. The increase in pyrolysis sintering temperature does not change porosity significantly; porosity that occurs in carbon-ceramic composites at each composition ratio tends to be stable at adjacent values. The higher the sintering temperature, the higher the electric current that can flow in carbon ceramics. The micro-features contained in the composite bulk show porosity and cracks, and disconnection of connectivity between the filler carbon powder
