“…In our prior investigations, we ascertained that the zeolite structure underwent ion exchange with Co and Zn ions, followed by structural collapse at elevated temperatures, subsequently leading to recrystallization. 15,33 The predominant phase in the sample is Co-willemite, as indicated by the red bars corresponding to the experimental peaks in the figure, a result corroborated by the reference Crystallography Open Database(COD) (900-7628). Conversely, the reference COD for gahnite is 900-6270.…”

“…The XRD pattern acquired from our specimen reveals the presence of two distinct phases: Co‐willemite (Co x Zn (2− x ) SiO 4 ) and gahnite (ZnAl 2 O 4 ). In our prior investigations, we ascertained that the zeolite structure underwent ion exchange with Co and Zn ions, followed by structural collapse at elevated temperatures, subsequently leading to recrystallization 15,33 .

“…The critical influence of precursor quantities of cobalt and zinc oxide on phase composition and pigment coloration is highlighted by our investigations, both present and prior. Furthermore, calcination temperature emerges as a crucial parameter, with temperatures below 900°C failing to yield the blue pigment, while higher calcination temperatures result in enhanced stability of the blue pigment structure 15 …”

This study presents the successful synthesis of a vibrant blue nanopigment derived from the metastable structure of Na‐heulandite zeolite. Employing ion exchange and coprecipitation methods with cobalt and zinc ions, followed by thermal treatment at 1100°C, resulted Co‐willemite and gahnite phases, confirmed by x‐ray diffraction and Rietveld refinement. Optical analyses verified the blue coloration, with cobalt ion transitions evident. CIE L* a* b* colorimetric analysis placed the pigment in the blue region (L* = 49.19, b* = −22, a* = −11). Application to ceramic tiles, followed by sodium dodecyl sulfate (SDS) modification, produced a nearly superhydrophobic surface (contact angle 140°, sliding angle 8°), attributed to the nano–micro structure and SDS–silica interaction. Field emission‐scanning electron microscopy images confirmed the pattern‐like surface with small patterns. These findings indicate potential self‐cleaning capabilities when exposed to dirt or water, highlighting the research's promise in enhancing ceramic functionality.

This study intended to develop nano Cu-doped nano ZnO-modified ceramic glazes. In this scope, nano-sized ZnO and nano Cu powders were incorporated into a commercial glaze composition and then the modified glaze was applied to the surface using the spraying method. The glazed tiles were sintered in a laboratory furnace at 1210oC for 10 min. The surfaces of the sintered samples were analyzed using scanning electron microscopy. X-Ray diffractometer, surface profilometer and contact angle goniometer. The study examined the influence of varying levels of Cu doping on the microstructural evolution and formation of phases, surface roughness, as well as the contact angle. Additionally, wettability conversion experiments were conducted under UV light. As a result, the addition of Cu increased the presence of Willemite crystals and also increasing the quantity and size of Plagioclase crystals. The contact angle of the sintered commercial glaze coated surface was measured to be 51.8o. However, when nano ZnO was added, the contact angle reduced to 44.4o. Likewise, the contact angle of the Cu doped nano ZnO coated surfaces decreased even further to approximately 33o. The inclusion of nano ZnO in commercial glaze resulted in a decrease in the Ra value, while doping Cu led to a modest increase in the Ra value. UV irradiation resulted in a reduction in the contact angles of all surfaces.
