Utilization of Basalt Fibers as a Raw Material for Clay Ceramic Production

Influence of the Addition of Pore Foaming Agent on Mechanical and Thermal Properties of Porcelain Tiles

“…The variation of bulk density for all porcelain samples is similar to their linear shrinkage as exhibited in Figure 3b. The bulk density for P-Blank sample significantly increased with a progressive rise in temperature and achieved a value of 2.41 g•cm -3 at 1300 °C, which is consistent with that of typical porcelain-like bodies, 2.3 -2.5 g•cm -3 [4,18,20,27]. In addition, the incorporation of PMMA into porcelain bodies (P-PMMA) led to a decrease in the bulk density values due to the high level of porosity generation after the burnout of the organic particles during the firing process [5].…”

“…From the results, it can be seen that the strength values of porous porcelain samples prepared by adding PMMA 5 -20 wt. % sintered at 1300 °C is higher than the minimum strength values (35 MPa) of the ISO 13006 standard for ceramic tiles [4,27]. Thus, it is possible to use this type of porcelain for ceramic tiles in order to enhance the thermal resistance of building materials.…”

“…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].…”

“…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.…”

Effect of Feldspar Substitution by Basalt on Pyroplastic Behaviour of Porcelain Tile Composition

“…Supawan et al [40] explained, with the use of basalt as a raw material for ceramic production, that the addition of basalt increased the pore formation at temperatures above 1200 • C. They suggested that this phenomenon would result from secondary melting agents, such as CaO and MgO present in basalt, and that these oxides can increase or accelerate the liquid-phase densification. Pazniak et al [12] explained that the main mechanism that occurred during porcelain firing was the formation of the liquid-phase, wherein the degree of sintering was associated with the amount of molten mass present.…”
