Abstract:
One of the most important methods to synthesize the gold nanoparticles is based on reduction of a ‎gold precursor. In this paper, a typical procedure has been developed by employing a water solution ‎containing: a chelating agent (poly vinyl pirolidone, PVP), a reducing agent (Glucose) and adequate ‎amount of NaOH (for pH adjustment). Then, an industrial tile decoration process was simulated at ‎the laboratory scale and firing in a roller kiln at maximum temperature of 1040 ºC for 33 min. ‎transparent glaze was used as the medium. In order to properly compare the results, the suspensions ‎were diluted and applied, while taking care that each tile did receive the same amount of pigment. ‎Finally, XRD, UV- Vis, TEM and CIE- Lab were employed to characterize the obtained gold ‎nanoparticles.‎
Nano pigments synthesized are suitable for application as ceramic inks for digital decoration. A set ‎of magenta colors can be obtained in transparent glaze‏.‏‎ In compare to commercial products, the ‎good quality of synthesized samples can be noted‏.‏
