Abstract: It is evident from the extant results of experimental studies that the possibility of the manifestation of the template effect in the formation of anisometric micro- and nanoscale formations in oxide and composite systems has been analysed. In the synthesis of micro- and nanoscale oxide (complex-oxide) materials, compositions based on them, such as metal-oxide, in the combustion reactions of glycine-nitrate precursors, the template effect is observed, which promotes the formation of anisometric (extended) particles and their ensembles. In addition to the established facts documented in the extant literature, the occurrence of the aforementioned morphology (i.e. the synthesis of hydroxides and oxides of lanthanum, neodymium, praseodymium, holmium, samarium, yttrium, gadolinium, erbium and europium) has been observed in systems involving the synthesis of magnetic particles (e.g. strontium hexaferrite) and in other non-magnetic materials. In the process of synthesising magnetic complex oxides, this effect is instrumental in the production of high coercivity materials. The aforementioned effect is also applicable to samples of bactericidal composition of aluminium oxide with silver nanoparticles obtained in combustion reactions. The formation of anisotropic formations may be attributed to the presence of glycine, whose amphoteric molecules, in their zwitterion form, possess the capacity to establish ordered spatial structures that function as templates for the synthesis of target phases in combustion reactions.
Keywords: oxide materials, compositions, synthesis with salt forms, morphology, organic components, glycine
