The Role of MgCl2 in Preparation of SnO2, MgSnO3 and Mg2SnO4 Nanopowders
Tin oxide (SnO 2) ,MgSnO3 and Mg2SnO4 nanocrystals have been synthesized by one-step solid-state reactions. in the first step, The powder of SnCl 4.5H2O was mixed with MgCl2 and Mg(OH)2with weight ratio of Sn to Mg (1:1), (2:1) And (1:2) in an air atmosphere at room, and annealing temperature in this work were 200°C, 400°C ,600°C , 800°C and 1000°C . XRD patterns show the SnO2 , MgSnO3 and Mg2SnO4 particle size of synthesized powders by MgCl2 were 3 nm, 4nm and 27 nm respectively. In fact the excess amount of Mg role of crystallite growth inhibitor in SnO 2. this method is a simple ,inexpensive ,efficient and economic preparation for SnO 2, MgSnO3 and Mg2SnO4 nanoparticles with adjustable grain sizes in the range of 3-44nm in high yield. This article shows the role of mass MgCl2 in producing of SnO2 nanoparticles.
