| Popis: | Small pellets with differing mullite contents were prepared by a conventional ball-milling and dry-powder pressing technique, followed by firing at temperature of 1300°C and 1600°C for four hours. Kaolin processing waste and high purity aluminum hydroxide were used as starting materials. The sintered samples were examined using X-ray diffraction to determine the weight percent of each identified phase. The results showed that the percentage of mullite in kaolin processing waste can be increased by introducing additional aluminum hydroxide. It was found that sintered samples yielded best results when derived from both types of kaolin processing waste with 40wt% of aluminum hydroxide and a firing temperature of 1600°C. |
