The Effect Of Group-Two Metal Oxides On The Properties Of Ground Enamels

The effect of alkaline-earth metallic oxides on the properties of glasses and glazes have been studied by many workers, however, the role of these oxides in round enamels for steel products has not adequately been studied. The presence in enamels of alumina, fluorine and sometimes boric oxide greatly hinders the study of such melts and experiments do not always succeed in revealing the general rules which connect the magnitude of the iconic radius with the properties of the enamels. In this paper, the author reports on the action of the group two oxides on fusibility, viscosity, surface tension, wetting angle and other properties of enamels of the type No 27 (ground enamel).
