Multi-component metal powder

The glycine/nitrate process (GNP) is a self-combustion method using glycine as fuel and the nitrates of metal components of the material to be synthesized as oxidant, which can prepare a high specific surface powder with single phase composition in very short time. It is especially appropriate for the fabrication of multi-component system such as doped perovskite compounds [11]. Moreover, this process is easily operated and cost-effective. 

This method is suitable for the preparation of multi component oxides of high purity at low temperatures. It is well known that the ratios of the reactants and the conditions of the polyesterification have a considerable influence on the purity and properties of the final product [27-29]. Yang et al. [28] investigated the effect of CA metal ions molar ratio on the synthesis of Lao 6 Sro ssMnOs powders by polymerizable complex process, showing that with the ratio of 4 the powder exhibited a pure phase of perovskite, with nanometric particle size and high specific surface area. According to Gaki et al. [29] the molar ratio CAimetal ions = 2 is the most favorable for the synthesis of LaMnOs.
