A fast and facile wet chemistry method has been developed for preparing monodispersed silver coated copper composite particles.
Copper powder loaded with silver particles morphologies range from individual particles to small islands, to the continuous multi-layers structure with Ag+ concentration increases.
Abe, Surface coating of microparticles with tungsten carbide by using the barrel sputtering system, Vacuum, 83(2008) 633-636. ]) etc. wet chemistry method is a common method to produce the nanomaterials in which a metal salt is reduced to metal onto a surface from a solution without the use of an electrical potential.
In the present work, a wet chemistry silver-coating process was employed on copper particles and copper powder loaded with Ag particles was prepared.

The major influences on the process are caused by the mechanics of the polishing machine, by the chemistry (composition of the glass, as well as the polishing suspension of water and polishing grains, CeO2) [1], [2] and by the material and structure of the polishing pad.
Apart from the mechanics of the polishing machine [5], [6] and the polishing grain substrate [7], the chemistry of the polishing suspension has a major impact on the polishing result.
Simulation of chemical processes in aqueous solution To examine the complex chemical processes in the aqueous solution (polishing suspension), the polishing process is modeled with the software HSC Chemistry from Outokumpu.

Further analysis of the sample focused on its composition and structure.
Overall, these findings provide valuable insights into the composition and structure of manganese compounds, which can aid in the various applications.

Such a zeolite-like structural feature may had interesting bulk-chemistry applications, especially heterogeneous photocatalysis[4].
Low-angle X-ray diffraction pattern of extraction sample 1 and 2 exhibited a broad peak (Fig.1(1,2)), explained being some well-ordered mesoporous structure.
The microwave and extraction method could help to synthesize uniform mesoporous structure materials.

Such factors as the Na2O/SiO2 ratio, crystallization temperature and time had effects on the structure and property.
The structure contains isolated cavities, called the β-cages in zeolite chemistry, which are usually occupied by cations, certain guest molecules like water, or cation–anion pairs.
Ionothermal synthesis, where an ionic liquid is both the solvent and source of the template, provides opportunities to develop new synthetic routes that are based on different chemistry to traditional hydrothermal approaches[3].
The structure and morphology were characterrized by means of XRD, IR, SEM.
