“…6), a clear difference between the bands yielded for the samples synthesized with AcH and HPA was observed. In samples with acetic acid appear bands characteristic of zirconia, located at 1050, 1030, 956, 650, 620 and 463 cm -1 (Agoudjil et al, 2008;Chavez Granados, 2005). The band around 1030 cm -1 indicates the bending vibration of OH end groups of the chemical bond O-Zr-OH in the material structure.…”

Zirconia is a widely used multifunctional material. Its interesting properties, such as high chemical resistance, thermal stability and high mechanical toughness, have turned this material into object of study within fields such as optics, electronics, and magnetism, among others. In recent years, the chemical properties of zirconium oxide have been used, mixed with silicon, in order to obtain more stable and robust mixed oxides, with the final application of toughening ceramics. These properties are related to the degree of mixing of the components at molecular level, therefore, the linking between Si-O-Zr. Considering the effective antimicrobial capacity of silver nanoparticles, their incorporation into different materials is very interesting, acting as biocides. The objective of this work is to obtain zirconium oxides by the sol-gel technique, using zirconium n-propoxide as precursor, and also to study the effect of different solvents (water, ethanol) and the use of various acid catalysts in the synthesis [acetic acid and a heteropolyacid (HPA), as the phosphomolybdic acid (H 3 PMo 12 O 40 )] on the physicochemical properties of the obtained solids. Finally, the addition of a silver salt was carried out into the sample with acetic acid and heteropolyacid as catalyst, in order to incorporate it as antimicrobial filler in paints. The obtained materials were characterized by SEM, XRD, FT-IR, textural properties through the absorption of N 2 (S BET ) and potentiometric titration with n-butylamine. Homogeneous solids were obtained in all the synthesis with acetic acid as catalysts. In addition, x-ray diffraction diagrams of amorphous solids were observed. The values obtained of surface areas are influenced by the variables of synthesis. The characteristic bands of zirconia were observed by FTIR in the solids synthesized. The results show that the solids environmentally synthesized are promising additives for use in paints.

“…Most applications in wastewater cases have been carried out using polymeric membranes, however, inorganic membranes including ceramic membranes have replaced organic polymeric membranes in wastewater treatment [3][4][5][6]. Ceramic membranes are produced from inorganic materials such as aluminum oxides (Al 2 O 3 ), silicon carbide (SiC), and zirconium oxide (ZrO 2 ) [7][8][9][10][11][12][13][14][15][16]. Ceramic membranes are very resistant to aggressive media (acids and strong solvents).…”
