초록
In this study, research was made on the production of white and translucent ceramics with a low water absorption and high resistance using waste dolomitic sepiolite, cullet and calcite through fast firing under operational conditions. For this purpose, 4 different recipes were prepared. The recipes were first dry ground and shaped with a dry pressing method. The shaped samples were then fired in a fast firing kiln at 1140 ο C for 70 minutes. Strength, water absorption, porosity and color measurements were made on the fired samples as well as mineralogical and microstructural examinations. Consequently, diopside and amorphous phases and diopside and akermanite based ceramic structures were produced using the waste materials through fast firing at 1140 ο C. L* values of the fired samples were found to be between 92.30 and 95.40. In the samples with the akermanite and diopside phases, the ratio of dissolution was found to be higher in acids than samples containing the diopside and amorphous phases. Consequently, highly white and translucent ceramics with a low water absorption capacity were obtained using the waste materials used through fast firing.
