Complexation is a chemical reaction that produces coordination complexes.<\/p>
A coordination complex is a chemical compound consisting of a central atom or ion, which is usually metallic and is called "coordination centre", and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents.<\/p>
During a complexation reaction, chemical bonds are formed between a central atom or ion and other chemical species in numbers greater than the oxidation number of the atom or the central ion.<\/p>
In Ceramics, complexing agents consist of particular chemical molecules (sodium salts) equipped with functional groups containing atoms that provide the system with a very negative electronic charge.<\/p>
When added to the ceramic mixture, the complexing agents release sodium (monovalent cation) preferentially attracting multivalent cations. The result of this electrostatic process facilitates cation exchange with a consequent increase in the distance between the particles and a decrease in viscosity, containing if not eliminating flocculation phenomena.<\/p>","protected":false},"excerpt":{"rendered":"
