Dissolution mechanism of Al2O3 in refining slags containing Ce2O3

alumina rod (6mm in diameter) was pre-heated above the slag surface for 102 min, subsequently immersed in the slag. After predetermined time, the rod was withdrawn from the slag and rapidly pulled out of the furnace. The slag layer adhering to the surface of the alumina rod was removed by dipping the same in HCl dilute solution.

Effect of CaO/Al2O3 Ratio of Ladle Slag on Formation Behavior

The slag was prepared with a mixture of reagent grade CaO, calcined from CaCO 3 at 1 273 K, SiO 2, Al 2O 3, MgO, and CaF 2, and powder mixture was melted using a vertical resistance furnace at 1 873 K. The pre-melted slag (50 g) was injected through the quartz tube. Compositions of the pre-melted slags are listed in Table 1 and shown in Fig. 2.

SULFURIC ACID RESISTANCE OF HARDENED CALCIUM ALUMINATE CEMENT

Calcium aluminate cements containing blast furnace slag are considered to be used as alternative material. The present study is to discuss the mechanism of sulfuric acid resistance between calcium aluminate cement containing blast furnace slag and ordinary Portland cements. CH and C-S-H were mainly produced in ordinary Portland cement.
