Características microestructurales de varistores del sistema ZnO-BaO-P₂O₅

Boletín de la Sociedad Española de Cerámica y Vidrio, 1999
Ceramic materials based on the system ZnO-BaO show a great potential for varistor applications. However, the BaO rich phase located at the grain boundaries shows high solubility in water which causes severe damage of the materials.
