Manganese induced ZrSiO4 crystallization from ZrO2SiO2 binary oxide system

Effect of halide mineralizers on monodisperse spherical zircon powders

“…Since zircon as a distinct ternary metal oxide has acquired many established applications as stated in the introduction, the MSZ zircons will be particularly attractive in some emerging areas such as biomedical compatible materials and catalyst supports, etc. Meanwhile, considering the finer sizes (against 3-20 μm in common zircons [21][22][23][24] ) and low specific areas, the MSZ zircons will also be of special interest in the synthesis of advanced ink-jet zircon pigments, such as blue V-ZrSiO 4 , yellow Pr-ZrSiO 4 , and pink Fe-ZrSiO 4 . 23,24,54,55 These investigations will be anticipated in future work.…”

“…Furthermore, expensive Zr/Si alkoxides and elaborate processing controls are another two prerequisites in synthesis. In other approaches, such as hydrothermolysis or solid calcination‐involved multi‐step fabrication, zircon crystallization becomes more uncontrollable, and hence powders were generally produced with the morphologies of being tetragonal dipyramidal, layered, donut‐shaped, or irregular and also with large sizes (averagely 3‐20 μm) and wide size distributions 21‐24 …”

[21][22][23][24] In the synthesis of zircon, a fluoride is normally employed as a mineralizer to catalyze the reaction of zirconium and silicon sources and remarkably affects the crystallization process and final resultants in morphology and composition, either in a solid-or liquid-based reaction. In a solid-based synthesis, a fluoride mineralizer first reacts with the Si species to form gaseous SiF 4 , 1,25,26 which then reacts with Zr to produce zircon at temperatures above 800 °C, typically 1000-1600°C.…”

Formation of zircon‐type (Zr,Ti)1−x(Dy)x(SiO4)1−x(PO4)x solid solution and their optical and magnetic characteristics

“…14 Praseodymiumsubstituted ZrSiO 4 , a yellow pigment, is the most investigated material, and titanium (Ti 4+ )-, iron (Fe 3+ )-, and manganese (Mn 2+ )-substituted ZrSiO 4 have also been reported. [15][16][17][18] ZrSiO 4 formation is usually reached through a solid-state synthesis route that mainly depends on the self-stabilization mechanism by hosting impurities in its structural lattice. The ability to trap radioactive and rareearth elements in the lattice to retain a solid solution of zircon is also considered a significant advantage.…”

“…[19][20][21] A series of study implemented by the authors articulate the formation of pure ZrSiO 4 by accommodating impurities in the form of Ti 4+ , Fe 3+ , and Mn 2+ , and moreover, the enhanced mechanical properties displayed by these materials and their suitability in biomedical applications were also reported. 16,17 The present study attempts to form Dy 3+ /PO 4 3− cosubstituted ZrSiO 4 for potential application in hard tissue replacements. The rationale to choose Dy 3+ as a choice of dopant in ZrSiO 4 is mainly based on its visible luminescence and magnetic resonance imaging (MRI) features that is expected to fetch multimodal imaging capabilities to the resultant material.…”
