“…Several compositions of porcelain stoneware have been reported [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. 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. However, only a few works focused on both the mechanical and thermal properties of claybased materials [5,7,24].…”

Among of pore forming agents, starch seems to be an appropriate pore foaming agent because it is a natural biopolymer, with easy handling and processing, good commercial availability relatively low cost.…”

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.

Estimation of Nanoporous Au Young’s Modulus from Serial Block Face-SEM 3D-Characterisation

et al. 2022

Nanoporous Au has been subjected to serial block face-scanning electron microscopy (SBF-SEM) 3D-characterisation. Corresponding sections have been digitalized and used to evaluate the associated mechanical properties. Our investigation demonstrates that the sample is homogeneous and isotropic. The effective Young’s modulus estimated by an analytical multiscale approach agrees remarkably well with the values stated in the literature.

“…Due to its high mechanical strength, durability, low water absorption and translucency, porcelains apart from household they are extensively used for science and engineering applications [13]. Porcelain tiles that were previously used for floor are now used as ornaments in houses and internal wall, thus a slightly different properties are required for these applications such as mechanical designs that are directly related to the body microstructure [14].…”

Palm oil fuel ash (POFA) is a by-product from thermal power plant where palm kernel, shell and fibre used as fuel to generate electricity and disposed with no economic value. POFA is used as quartz replacement in the production of porcelain. POFA was dried in an oven for 24 hours at 110 °C, ground at a speed of 250 rev/sec for 12 hrs. Some of the POFA amount was treated with 2 Molar of HCl acid and some was kept untreated. Both treated and untreated were substituted with quartz at 15 wt% and mixed with porcelain composition and dry pressed into pellets at a mould pressure of 91 MPa and sintered at 1150 °C, 1200 °C and 1250 °C for 2 hrs soaking time respectively. XRF revealed that, POFA has similar chemical composition with quartz. The highest compressive strength, bulk density and Vickers microhardness being achieved at sintering temperature of 1150 °C using treated sample with the values 169 MPa, 2.432 g/cm3 and 774 HV respectively. HCl treated POFA is a good candidate for quartz replacement and 1150 °C was the best sintering temperature.
