“…The material characterization has been conducted on the prepared YSZ at 4.5%, 8%, and 10% of mol yttrium ions. The analysis by X-ray diffraction equipped with le bail refinement and the results have been published in our previous paper (Rahmawati et al, 2016). The yttria-stabilized zirconia at 4.5%, 8%, and 10% produced from zircon sand were crystallized in the same structure, i.e., cubic, tetragonal, and monoclinic with the space group of F M 3 M, P 42/ N M C z, and P1 (Rahmawati et al, 2016).…”

“…Zircon, ZrSiO4, is a stable molecule due to the strong bond between zirconia and silica. Some methods to extract zirconium from zircon are caustic fusion or with soda ash (El-Barawy et al, 2000), heat plasma dissociation (Ananthapadmanabhan et al, 1993), thermal decomposition (Pavlik et al, 2001), caustic fusion (Rahmawati et al, 2016) and mechanochemical processing (Puclin et al, 1995).…”

Doping yttrium ions, Y 3+ into ZrO2 produced Yttria-Stabilized Zirconia, YSZ. Various amount of yttrium ions could provide different ionic conductivity. This research investigated electrical conductivity of various YSZ composition, i.e., 4.5; 8.0 and 10% mol yttrium in ZrO2. The ZrO2 powder used was synthesized from zircon sand, a side product of tin mining plant, Bangka Island, Indonesia. Structural investigation on the prepared YSZ found that yttrium ion doping has changed the crystal structure of ZrO2 from monoclinic to cubic, even though the monoclinic and tetragonal are also still exist. The Y 3+ doping changed the cell parameter of ZrO2 crystal. It indicates that the Y 3+ entered into the ZrO2 structure and produced vacancy sites. The highest ionic conductivity is provided by 8% mol Yttrium doping or 8YSZ, i.e., 2.74×10 -4 S.cm -1 at 700 o C with an activation energy of 0.741 eV.

“…The use of zircon in the production of zirconia is quickly increasing because it is capable of resisting high temperatures and chemical attacks, creating good refractory for furnaces, steel ladles, and foundry sand used [10]. The production of zirconia is simple, and it requires low capital and operational cost by concentrating the zircon through caustic fusion [11][12]. These facts show that the caustic method is essential for compound production.…”

The zircon powder from Zircon Minerals Malaysia is a pure premium grade zircon sand milled 1.5 µm that contain ZrSiO4, ZrO2, HfO2, SiO2, Al2O3, TiO2, and Fe2O3. The monoclinic zirconia powders were synthesized from the zircon sand of Zircon Minerals Malaysia, by caustic fusion method at calcination temperatures between 500 °C to 800 °C. The as-synthesized zirconia was characterized through X-Ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric and differential thermal analysis (TG-DTA), and X-Ray fluorescence (XRF) techniques. The XRD results show two monoclinic phases of microcrystalline zirconia. Zirconia that was calcined at 600 °C obtained the highest value of ZrO2, which was 54.48%; followed by zirconia calcined at 700 °C, 800 °C, and 500 °C, which obtained the ZrO2 values of 53.58%, 52.41%, and 51.53%, respectively, based on the XRF analysis. As-synthesized zirconia showed monoclinic phases where the surface areas were 0.0635 m2/g, 0.135 m2/g, 0.0268 m2/g, and 0.0288 m2/g, for zirconia calcined at temperatures of 500 °C, 600 °C, 700 °C, and 800 °C, respectively. The surface structure of the powder that had been calcined at 600 C showed similarities with the commercial zirconia. The similarities of the synthesized zirconia and commercial zirconia showed that the zirconia powder could be synthesized using zircon sand by caustic fusion method, even though the content of zirconia was lower compared to that of the commercial zirconia powder.
