Preparation of NaIn(WO4)2 nanocrystals and a charge for crystal growth via the free-of-rubbing mechanical activation of the Na2CO3−In2O3−WO3 system

The pollution-free or free-of-rubbing mechanical activation of the Na₂CO₃–In₂O₃–WO₃ system resulted in the formation of the nanosized crystallites (nanocrystals) of NaIn(WO₄)₂ at 698K (425°C). The use of very hard milling tools of mechano-chemical reactors allows one to offer also a new way of charge preparation with a composition and structure suitable for growing the bulk crystal of NaIn(WO₄)₂.
