“…The composition in wt. % of the frites, were chosen from reference [14], as these types of glasses are very sensitive to phase separation, the selected compositions were chosen from the center of compositional triangle proposed by [14] to avoid the opal appearance (Fig. 1).…”

“…It has been demonstrated, that the major effects in the melting kinetics and the major variations in reaction paths are directly attribute to the particle size distributions of the batch components [12]. In this work, the ne size sample was generated by upgrading of Halid bearing Zinc Oxide concentrate from the recycling of Zn ingots dusts [13].…”

The frites by mole fraction of 2.5 SiO2, 0.20 Al2O3, 0.15 B2O3, 0.15ZnO, 0.17K2O, 0.67CaO systems in three ratios of S including 0.37(denoted by F1frites ),0.31(F2), 0.24(F3) (S=K2O/CaO+ZnO) were studied. ZnO powder with 500 nm (N series) and >1μm sizes (F series) opted from the recycled Zn ingots dusts and commercially ZnO respectively, were used as the raw materials. By decreasing the S ratio, the Molar Volumes of frites were decreased, The glass transition ΔTg(=-154ºC), and the crystallization temperatures ΔTp (=+17ºC) values were decreased and increased respectively. It was shown that the GS (glass stability) values are independent of the Zinc Oxide's powder size, while the Molar Volumes of N series were lower than the F ones. The Zinc Silicate (Willemite) beside Anorthite and Parawollastonite phases were crystallized in the resulted glazes. The hardness values were in 700-850 Hv range, the transparency and whiteness were higher than 80 and 60 respectively.

“…This causes better spreading, uniformity of the glass layer, and allows the production of the glaze without unevenness. The gloss of the glaze depends on the surface roughness, which depends on the viscosity of the glaze [41]. is 30% higher than that of other glazes.…”

This study is focused on the treatment of waste sludge from a zinc chloride production in order to prepare iron-rich pigments usable for a production of glazes. In galvanizing plants,, yellow waste sludge containing significant amount of ZnO, Cl, and Fe2O3, is formed. This raw waste sludge cannot be used as a pigment in glaze. Therefore, three methods of treating this material were proposed: a) washing with H2O, b) calcination at 180 °C and washing by H2O, and c) calcination at 900 °C and washing by H2O. These methods helped to reduce Zn and Cl content up to 97%. According to X-ray fluorescence analysis percentage of Fe2O3 increased from ~41% to ~98%. X-ray power diffraction analysis confirmed the formation of α-Fe2O3 (hematite) in the pigment prepared. Scanning electron microscopy with Energy dispersive X-ray analysis showed clusters of rounded particles, and also the change in size of particles after calcination was observed. Particle size, specific surface area, and density measurements together with thermogravimetric and differential thermal analyses were performed. Pigments prepared from the waste sludge were added to transparent glaze in amounts of 1, 5, 10, and 15 wt.%. Pigment-containing glazes were applied by spraying on fired ceramic tiles and then fired at 1060 °C. Color of glazes was determined by (Commission Internationale de l’Eclairage) CIE L*a*b* coordinates as colorless, light brown shades, brown-red, brown-yellow, and deep red-brown. Comparison with colors of glazes prepared using commercial pigments was also performed. Waste sludge can be used to prepare pigments and glazes containing pigments as an alternative to commercial products.

“…Regarding the surface grade and hence the aesthetic behaviour of a glazed tile, it was demonstrated the influence of the particle size distribution [20] and the composition of the original glassy matrix on microstructure and crystalline phase content on the surface of glass-ceramic glazes. [21] Moreover the formation of defects is hard to control and could derive by external factors, for example by pollution [22] or internal factors, in most cases the composition, that often leads to an unsuitable interactions among the glass components [23] [24] .…”
