Abstract
Sono descritte composizioni sigillanti per ossido di alluminio, concentrati e procedimenti in cui esse vengono impiegate, le quali comprendono un sale di metallo alcalino terroso e certi composti aromatici solfonati. Si ottengono inaspettati miglioramenti nella qualità della sigillatura impiegando le composizioni dell'invenzione ed in sostanziale assenza di formazione di macchie.Vantaggiosamente, le composizioni sigillanti acquose della presente invenzione possono essere prive di cobalto e di nichelio, possono essere preparate da acqua corrente e possono essere impiegate a temperature inferiori al punto di ebollizione.
