Webb16 okt. 2004 · There are three basic reactions for the Pechini process—formation of metal chelates, estification, and polymerization—occurring during the formation of the polymeric precursor. In our experiments, the citric acid and ethylene glycol … A process related to the sol-gel route is the Pechini, or liquid mix, process (named after its American inventor, Maggio Pechini). An aqueous solution of suitable oxides or salts is mixed with an alpha-hydroxycarboxylic acid such as citric acid. Chelation, or the formation of complex ring-shaped compounds around the metal cations, takes place in the solution. A polyhydroxy alcohol is then added, and the liquid is heated to 150–250 °C (300–480 °F) to allow the chelates to polyme… trying to play cool

WebbPechini process was known as an excellent method for the synthesis of LiNiO2powder. Compared with the result of solid state reaction using NiO and Li2CO3as reactants, Ni2O3was the new compound found in Pechini-processed powder. WebbPechini, M.P.et al. [19]. reported that, the most significant advantages of Sol-Gel Pechini method process is its simplicity and the low-temperature precursor handling. This results in the fabrication of nanopowders with excellent purity and uniformity, as well as precise control of the final composition of the material.
