Investigation of the ceramic tiles that contains boron frit

다국어 초록 (Multilingual Abstract)

The floor tiles contain porosity depending on the production process. Therefore, water absorption is higher for the floortiles. The water absorption permeability leads to problems such as visible spots on the surface of the products after laying.
This situation returns to firms in the customer complaint. Impervious engobe has been investigated as a possible solutionto this problem. In this study, a more sintered engobe was tried to be obtained. The amount of glassy phase increased dueto increased boron frit, so water permeability decreases were observed. The permeability problem has been occurred in thesamples which have prescription rates below 20% boron frit. XRD,SEM,DTA,Thermal Microscope and expansion analysiswas performed. According to the results obtained from SEM images of impervious engobe samples were found to be morecompact. This shows that spaces have been closed due to increasing amount of the boron frit. The lower sphere temparaturehave observed in the thermal microscope analysis for the engobes which contain more boron frit. So the sintering temperaturehas been reduced and thus the floor tiles permeability has been reduced.
