ROCHA-RANGEL, Enrique; BECHER, Paul F.  y  LARA-CURZIO, Edgar. Unión entre metales y cerámicos. Rev. Soc. Quím. Méx [online]. 2004, vol.48, n.2, pp.146-150. ISSN 0583-7693.

In this work a review is made about the different factors that affect the wettability of liquid metal-ceramic systems, making special emphasis in the Al-Al₂O₃ system. It is suggested a chemical modification of the interface liquid Al-Al₂O₃ through the use of elements known as lanthanides, which have strong affinity to oxygen. Lanthanides form a thin oxide film at the interface, diminishing in this way its surface energy, so wettability and therefore union between metal and ceramic is improved.

Palabras llave : Union; wettability; metal-ceramic.
