Abstract

This research aims to study and investigate the effect of sintering temperature and clay addition towards glass ceramic produced from recycle glass by using pressing method. Soda lime silicate glass is used as main raw material and ball clays act as filler for glass ceramic fabrication. Firstly, the recycle glass bottles were crushed by using hammer until they passed through a sieve of less than 75μm. The glass powder was than mixed with ball clays with weight percent ratio of 95:05, 90:10 and 85:15. Then, green ceramic article is formed using uniaxial dry pressing method. Green is referred to the unfired ceramic. In this study, the sintering temperature are varied at 750oC, 850oC and 950oC.The microstructure and phase present in glass ceramic is analyzed using scanning electron microscope (SEM) and x-ray diffraction (XRD). The physical properties are determined using porosity, density measurement and water absorption test. Mechanical analysis is carried out using microhardness test to determine its mechanical properties. The results indicated that with 10 weight percentage of clay addition and sintering temperature of 850°C, glass ceramic produced with good and suitable physical and mechanical properties. It is showed that the increasing of sintering temperature and percentage of clay addition had increasing hardness and density of sintered glass ceramic. Hence, it will decrease the water absorption and porosity of the glass ceramic. Due to the results obtained, the optimum sintered temperature and percentage clay addition was found at 850°C with 10 weight percent clay addition. This is because at this point, the mechanical and physical properties gives the less percentage amount of porosity and water absorption and higher on bulk density and microhardness compare than the others. Through the study, the enhancement of fabricated glass ceramic could be applied to the structural applications through the advantage of mechanical and physical properties performance of hardness, water absorption, porosity and density.
