บทคัดย่อ
This study compared the physical properties of ceramic floor tiles made from kaolin and quartz with those made from glass cullet and feldspar prepared at sintering temperatures of 1100ฐC and 1150ฐC. In addition, the effects of using lithium carbonate and glass cullet instead of feldspar to reduce the sintering temperature of ceramic floor tiles were studied. The base body was prepared from Ranong kaolin, feldspar and quartz. Feldspar was replaced by glass cullet at proportions of 0% and 100%. Lithium carbonate was used as an additive at proportions of 0%, 0.5% and 1.0%. A total of six formula samples were prepared and fired at 1100ฐC and 1150ฐC. Shrinkage, water absorption, and color (CIELab) were measured in the fired samples. The results showed that at 1100ฐC, the shrinkage of feldspar samples (0.80-1.41%) was less than that of glass cullet samples (5.19-5.84%). The water absorption of feldspar tiles (5.14-26.62%) was more than that of glass cullet tiles (13.92-16.12%). At 1150ฐC, the shrinkage of feldspar tiles (10.85-11.20%) was more than that of glass cullet tiles (8.35-9.01%). The water absorption of feldspar-added samples (0.16-0.30%) was comparable to that of glass cullet tiles (0.15-0.30%). Moreover, the brightness (L*) of feldspar tiles (83.43-84.32%) was greater than that of glass cullet tiles (76.04-76.48%). It was also found that the sintering temperature of the tiles could be further reduced by adding lithium carbonate to the glass cullet. Glass cullet together with lithium carbonate were therefore shown to be promising raw materials if used to develop low water-absorption ceramic floor tiles, at a proportion of not more than 0.5% and at a sintering temperature of not more than 1150ฐC.
