| Popis: | Waste recycling was interested to both industrial and academic sectors. This study focuses on the use of sludge cake from wastewater treatment plant of a cosmetic industry as Magnesium oxide source. Cordierite obtains good chemical corrosion resistance, fine mechanical properties, good thermal conductivity, and most of all low coefficient of thermal expansion (COE) which is needed for ceramics industry. Magnesium is one of the main materials in cordierite, can be attained from different sources. In this research, Sludge cake from cosmetic industry was used as Magnesium sources for cordierite synthesis. The raw materials were ground, pressed, and sintered between 1200°C to 1325°C for 1 hour. The sampleswere investigated by X-ray diffraction technique and tested for thermal shock resistance, firing shrinkage, and water absorption. The XRD patterns showed that the increasing intensity of cordierite phase, the higher firing temperature presented the greater of cordierite phases. The findings were confirmed by the peaks of cordierite at 2q of 10.41° of samples when fired at 1325°C. It can be concluded that cordierite could be synthesized by using raw material from waste with other commercial raw material in different temperatures. Results showed that the sludge cake from wastewater treatment plant of Cosmetic Industry in Thailand is a promising as raw material and beneficial to Thai ceramics industry in terms of cost saving, competitiveness and environmental. |
