Recycling of the waste material plays an important role to preserve natural resources in the industrial world. Coffee husk ash is one of such forest industrial waste material. Replacement of feldspar by CHA in the production of ceramic electrical insulator was achieved as per industrial norms and augments the quality of the products. Physical and mechanical parameters water absorption, porosity, bulk density and strength of the sintered specimens were determined. The dielectric breakdown voltage was remarkably influenced by the porosity of the specimen. The structural characterization of the pure and CHA reinforced ceramic electrical insulator was performed using Scanning Electron Microscope (SEM) and X-ray diffraction (XRD), and thus results are correlated with physic[1]mechanical properties. The results indicate that the superior performance was achieved by CHA substituted insulator than an industrial standard insulator.
