Preparation of nanosized sodium–aluminum tungstate, NaAl(WO4)2

Phase equilibria in the system NaAl(WO4)2–NaCr(WO4)2

“…NaAl(WO 4 ) 2 was synthesized by the co-precipitation method, described in our previous paper [22]. Aqueous solutions of Na 2 WO 4 Á2H 2 O and Al(NO 3 ) 3 Á9H 2 O were mixed in a 3:1 molar ratio under intensive stirring.…”

“…Nanosized powder of non-doped NaAl(WO 4 ) 2 was successfully synthesized by us by a co-precipitation method [22]. In this way powders with the required dimensions, particle size distribution and particle shape were obtained.…”

Monoclinic superstructure in orthorhombic Ce10W22O81from transmission electron microscopy

“…Up to now no attempt has been made to obtain rare earth tungstates at a submicronic or nanometer scale, except the work of Furukawa et al (2006) on amorphous cerium tungstate powders with grain sizes around 15 nm. On the other hand, tungsten alloys are already available at a nanometer scale (Naik et al, 2011;Koseva et al, 2011).…”

Characterization of paramagnetic KHo(WO4)2 nanocrystals: Synthesized by polymeric mixed-metal precursor sol–gel method

“…Nanocrystalline form of this double tungstate was synthesized for application as sensitizing host for phosphors, upconversion host for laser [7] and transparent laser ceramics [8][9][10]. In the literature, only a few of KREW (RE = Gd, Yb, Eu) [11,12] and NaRE(WO 4 ) 2 (La, Gd, Tb and Al) [13][14][15][16] …”
