Reviews on Clay Geopolymer Ceramic Using Powder Metallurgy Method

Abstract

Inorganic polymers, commonly referred as geopolymers, are alumino-silicate materials which display superior physical and chemical properties with a diverse range of possible potential applications. Pure geopolymer matrix posses relatively low mechanical properties. The improvement on the properties can be made by focusing on the generation of ceramics from geopolymer. It’s a new world to explore yet with superior properties. The results showed the best curing temperature for clay geopolymers were at 60°C since it gained a fast initial setting. The hardened geopolymer clay will encounter physical metallurgy technique to be produced as geopolymer ceramic due to various high sintering temperature. It is proven that throughout heating the amorphous geopolymer transforms into crystalline phases with pure geopolymers demonstrates excessive shrinkage when sintered between 850 and 1000 °C.
