Beschreibung
Zusammenfassung:	An alkali-resistant refractory material has a surface layer characterized by a greater concentration of lithium than the bulk refractory material. L'invention concerne un matériau réfractaire résistant à l'alcali pourvu d'une couche de surface qui se caractérise par une concentration en lithium plus élevée que celle du matériau réfractaire volumineux.
