Translucent tile construction and its properties

Translucent tiles are among the tiles that have recently been featured. Passing part of the light is an important feature of these tiles. The passage of light from within, create a beautiful effect. In particular, it can be combined with LED, in which its beauty will be multiplied. In this research, the effect of using transparent frit and feldspar on porcelain tile composition was studied to obtain semi-transparent properties. Compositions of 10- %50 frits and feldspars were prepared by powder pressing and fired in a rapid roller furnace at 1150 ℃ and 70 minutes. The phase composition and microstructure were investigated by X-ray diffraction (XRD) and electron microscopy (SEM). A light spectrometric test was used to examine the light transmission and the white index of the samples was determined using a spectrophotometer. The flexural strength, density, and water absorption were also measured. The results showed that 50% frit, along with 20% feldspar, have a semi-transparent property and a better white index than other samples.
