“…At a sample preparation temperature of 1200 °C, two distinct behaviors were observed, depending on the ξ proportions of the precursors according to equation: (1 − ξ) ZnO + ξ Mg(OH) 2 . Figure a shows that for ξ = 0.33, hexagonal Zn 0.875 Mg 0.125 O (red peaks), and cubic Zn 0.68 Mg 0.32 O (blue peaks) phases were both observed with different proportions . According to its phase diagram at ambient pressure and below 1600 °C, the MgO–ZnO system is an eutectic type characterized by an extensive solid solubility of ZnO in the periclase phase (MgO‐rich) and a restricted solubility of MgO in the zincite phase (ZnO‐rich).…”

Zn 1-x Mg x O microcrystals are produced in the 0.15 ࣘ x ࣘ 1 composition range by calcination of ZnO + Mg(OH) 2 after hydro micro mechanical activation according to the patent WO2018065735A1. The structural properties of the samples have revealed the cohabitation of wurtzite and rock-salt phases for x values ranging from 0.15 up to 0.6 with a clear increase of the proportion of cubic phase with x. A single cubic phase is observed in the range 0.66 ࣘ x < 1. From the purity of these samples produced at very low cost, it is expected that they will be used as precursors for growth of advanced light emitters integrated into an already existing process as they exhibit exceptionally efficient (and robust with T) light emission in the ultraviolet region.

“…Meanwhile, the sol-gel method includes the use of complex precursors as the raw materials. For instance, synthesis of nanoparticles of magnesium and titanium oxides [5][6][7][8] has been reported recently. Despite its potential in controlling the size and shape of the products, the sol-gel process usually is time-consuming and costly.…”

A set of ceramic powders has been synthesized using a "bottom-up" approach which is denoted here as the dissolution method. The raw materials were metal powders or minerals. The dissolution media were strong acid or base solutions. In the case of metallic raw materials, magnesium and titanium powders were separately dissolved in hydrochloric acid to obtain their precursors. They were then dried, washed, and calcined in air at various temperatures to produce pure MgO and TiO 2 nano-powders. Pure MgTiO 3 nano-powders by mixing the precursors at the stoichiometric ratio and calcining the dried mixture at a temperature as low as 700°C have also been successfully synthesized. In the mineral case, local zircon sand was used as the raw material. A standard procedure to extract the "clean" and pure zircon powder was applied which included washing, magnetic separation, and reactions using hydrochloric acid and sodium hydroxide. A pure zircon nano-powder was obtained by applying mechanical ball-milling to the zircon powder. The zircon powder was also chemically dissociated to give amorphous silica (SiO 2 ), cristobalite, amorphous zirconia (ZrO 2 ), and nanometric tetragonal zirconia powders.
