Abstract
Inventia se refera la un procedeu de obtinere a oxizilor micsti pe baza de lantanoide si metale tranzitionale, bazat pe descompunerea termica a combinatiilor complexe polinucleare a acestor metale. Oxizii micsti obtinuti conform inventiei se caracterizeaza prin proprietati supraconductoare sau catalitice superioare.
