“…They commonly consisted of clay 40 -75 %, feldspar 0 -18 %, and quartz 27 -50 % [3]. A lot of works have focused on the feasibility of replacing ceramic components by applying alternative raw materials [4,18], functional ceramic tiles with cleanability or photocatalytic properties [19] and the improvement of thermal property in order to increase the efficiency of construction materials in terms of reducing energy consumption for environmental friendliness [5,7,20]. For this purpose, pore forming agents including polymer particles [5,7], starch [21], carbon black [22], and biomass [23,24] have been widely studied as they can easily control the pore size as well as create the various porosity levels, leading to a reduction of thermal conductivity.…”

In this work, the effect of pore foaming agents (polymethyl methacrylate, PMMA) on the densification characteristics as well as mechanical and thermal properties of sintered porcelain samples was investigated. The influence of the PMMA content (0-20 wt. %) and sintering temperature (1000-1300 °C) were also studied. The result showed that the incorporation of PMMA in porcelain bodies led to a decrease in the density, while the porosity increased with an increase in sintering temperature. At 1300 °C, the bulk density and porosity of porous porcelain samples with PMMA additions (5-20 wt. %) were in the range of 1.91-2.23 g•cm-3 and 1.3-17.2 %, respectively. The flexural strength of the porous porcelain samples prepared by adding 5-20 wt. % PMMA and sintering at 1300 °C was in a range of 36-56 MPa, which is higher than the minimum strength values (35 MPa) of ISO 13006 standard for ceramic tiles. The thermal conductivity of porous porcelain is a function of the sintering temperatures. The increase in sintering temperature had a positive effect on the thermal conductivity of ceramic samples, because the thermal conductivity decreased significantly with increasing porosity levels. The addition of 20 wt. % PMMA in porcelain samples sintered at 1300 °C reduced the thermal conductivity up to 34 % while maintaining acceptable flexural strength values (~ 36 MPa). Thus, it is possible to use these porcelain samples as ceramic tiles in order to enhance the thermal resistance of building materials.

“…White enamel thermal conductivity can be compared with red stoneware tile [8,15]. The difference between the white and orange enamel are related not only with the pigments used for giving the color to the enamel but also with the optical absorption in the wavelength used in the thermal diffusivity.…”

In this study is determined the thermal conductivity of a commercial ceramic considering that this property on the building materials is an essential factor, and it is the primary indicator of the suitableness of the material in the energy transfer considering that this kind of materials has many applications as thermal insulations. In this sense and considering that a commercial tile is usually composed of three layers, a substrate, a so-called engobe layer, and an enamel layer. Likewise, the thermal properties of the different layers were obtained individually by using two photothermal techniques on the ceramic material; the ceramic tile density was obtained using the Archimedes method. The calculated values show a wide range of thermal conductivity values for the different layers, ranging from1.3 to 4 W m-1K-1.

“…It is due to several unique properties such as relatively low mass [1,2], low fractional density [3], low thermal conductivity [4], resistance to chemical attack [5], high specific surface area [6][7][8], high permeability and resistance to high temperature and thermal cycling [9][10][11][12]. For these reasons several materials are usually utilized for filters and membranes, as well as fuel cell electrodes, catalyst supports for biomaterials, piezoelectric materials, acoustically and thermally insulating bulk media [13][14][15].…”
