“…studied the influence of the crystal type of ZrO 2 on the formation of ZrSiO 4 . The effects of additives (Al 2 O 3 , 21 Fe 2 O 3 , 22 CaO, 23–25 and borosilicate glass 26 ) on the synthesis of ZrSiO 4 have also been studied. In addition, there are also research reports on the influence of other factors on the preparation of ZrSiO 4 , such as the way and degree of mixing, surface state, and particle size of raw material powders 27–29 .…”

Exploring the influence of sintering atmosphere on the formation of ZrSiO4 is of great significance. Herein, ZrSiO4 ceramics were prepared by the solid‐state reactive sintering method under different atmospheres (air, N2, vacuum, and Ar + 5%H2). The influence of sintering atmosphere on the phase and microstructure evolutions of the obtained ceramics was investigated. It was found that ZrSiO4 ceramics could be prepared under air atmosphere, whereas ZrO2–SiO2 glass ceramics were obtained under N2, vacuum, and Ar + 5%H2 atmosphere, which may be due to the fact that the oxygen‐deficient environment inhibits the transformation of ZrO2 to tetragonal phase (t‐ZrO2) and the crystallization of amorphous SiO2. The results demonstrated that t‐ZrO2 and c‐SiO2 were beneficial for the formation of ZrSiO4. The ZrSiO4 conversion fraction was up to 96.16% under air atmosphere at 1450°C for 6 h. Furthermore, the predominant formation mechanism of ZrSiO4 was the reaction between t‐ZrO2 and c‐SiO2.

Amang Zircon Sand from Amang Onn Sdn. Bhd. mineral company has a high composition of zirconium at 61.63 wt% and low silicon composition at 4.90 wt%. The high composition of zirconium in Amang zircon sand indicates the possibility to synthesise it into a zirconia. Zirconium was synthesised using alkali fusion method with different ratio of NaOH/ZrSiO4 to determine the optimum ratio based on the zirconium yield. Alkali fusion method is coupled with thermal treatment as it will produce a higher yield of zirconium with lower impurities. Then it will be leached with deionised water and hydrochloric acid (HCl). The synthesised zirconium was characterised through X-Ray fluorescence (XRF) spectroscopy, X-Ray diffraction (XRD) and particle size distribution (PSD) analysis. The XRF analysis after the fusion and thermal treatment shows a high composition of zirconium as well as great reduction of silicon. 1.2NaOH/ZrSiO4 is determined to be the optimum ratio as it has the lowest silicon impurity of 2.11 wt% and high yield of zirconium at 71.40 wt%. The low impurities will reduce the chance of cracking and maximising the efficiency of zirconia. It is supported by XRD patterns that are dominated by high zirconium peaks. The zirconium oxychloride obtained after acid leaching has a high zirconium composition. This shows that it is possible to use Amang zircon sand as a precursor to synthesis a zirconia using alkali fusion method with sodium hydroxide.
