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.

“…As mentioned in Section 3.1, the increase in talc amount enhances the densification, i.e. shrinkage due to liquid phase sintering, owing to reasons (1) and (2). This is why the saturated PI of the xT porcelains increases with increasing amount of talc.…”

“…Chemical composition differences affect densification with a liquid phase and the PD of porcelain through the evolution of a glass matrix and mullite crystals. Particularly, the influence of alkali and alkaline earth oxides on PD such as calcite, dolomite, magnesite and talc, 2) calcium oxide, 3) nepheline syenite, 6) spodumene, 7) waste glass, 8) and feldspar 4), 9) has been intensively investigated. The ratio of SiO 2 to Al 2 O 3 and the addition of certain minerals are other factors that have been investigated by using andalusite, 10) illite, 11) etc.…”

The water absorption (WA) and pyroplastic deformation (PD) of alumina-strengthened porcelain with talcaddition is examined to develop porcelain with optimized properties for a wide range of firing temperatures. An increase in talc amount enhances the porcelain densification, i.e. decreases WA and the increase in sintering shrinkage which accelerates PD, because it leads to an increase in the amount of liquid phase with a low viscosity during firing. On the other hand, talc and Gairome clay addition yields rigid crystalline microstructures in the glass matrix of the porcelain, which suppresses PD. As a result, optimized properties, i.e. WA less than 0.5% and pyroplastic deformation index less than 1.5 © 10 ¹6 mm ¹1 , are realized in porcelain with 2 mass % talc addition in a wide firing temperature range from 1240 to 1384°C.

“…From the STD-S porcelain tile spray-dry powder, two other compositions were formulated by adding fixed amounts of the fluxing aids, i.e., dolomite and magnesite: 2.1 wt % of dolomite and 0.7 wt % of magnesite, respectively. These fixed amounts were optimised from previous research [15].The new compositions were named D (dolomite addition) and M (magnesite addition). The spray-dry powder and each fluxing additive were mixed in a ball mill with water in a weight ratio solids/water 1:1 for 30 minutes, then the resulting suspension dried in a laboratory spray-drier (Büchi B-191) to obtain the dry powder.…”
