PROCESSING AND PROPERTIES OF POLYMER FILLED GEOPOLYMER CERAMICS FABRICATED VIA POWDER METALLURGY METHOD: A REVIEW.

Inorganic alumino-silicates polymers, known as geopolymers, result from the reaction of mineral clays or other source materials rich in silica and alumina with alkali silicate solution at 40-80 °C. Pure geopolymers, exhibits relatively low mechanical properties, which limit their usage in structural applications. Thus, this restriction could be overcome through the formation of ceramic geopolymers and the addition of fillers to improve their strength and toughness. This paper summarizes important research findings on the current knowledge of geopolymer ceramic, the addition of fine filler materials, and outlines potential effects using thermoplastic fillers on the physical and mechanical properties of clay-based geopolymer ceramic.
