摘要

"Process for obtaining crystalline eutectic ceramic fibers for medical and dental purposes and ceramic fibers thus obtained". The present invention relates to a process for obtaining crystalline gadolinium alumina / alumina-based eutectic ceramic fibers which are used in the medical-dental field, in particular to reinforce dental materials such as glass ionomers; acrylic resins, composite resins, porcelain, glass ceramics and dental ceramics. The invention also relates to gadolinium aluminate / alumina ceramic fibers having a highly crystalline microstructure composed of small diameter elongated microfibers (between 0.2 and 0.6 109) which give it anisotropy and high mechanical strength.
