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

The influence of sugarcane mulch on sand dune stabilization in Khuzestan, the southwest of Iran
ABSTRACT- Over the past 50 years, oil mulching has been a common technique for sand dune stabilization in the southwest of Iran (Khuzestan province). However, concerns over the release of heavy metals from oil mulching have led to the search for alternative mulches that are capable of stabilizing sand dunes without environmental hazards. This study investigates the feasibility of using sugarcan...
