Yd. Chung et Me. Schlesinger, INTERACTION OF CAO-FEO-SIO2 SLAGS WITH PARTIALLY-STABILIZED ZIRCONIA, Journal of the American Ceramic Society, 77(3), 1994, pp. 611-616
Calcia- and magnesia-partially-stabilized zirconia samples were corrod
ed under static and dynamic conditions in three slags from the CaO-FeO
-SiO2 system. Low-basicity and high-FeO slags corroded the samples by
leaching magnesia from the cubic phase in the specimen, causing its de
stabilization and ultimate dissolution. However, a higher-basicity sla
g which proved the most corrosive of the three promoted bulk dissoluti
on of the cubic phase instead, the rate of which was controlled by the
thickness of the adjacent slag boundary layer. The levels of sample c
orrosion both at and below the slag line are used to illustrate the ef
fects of experimental variables, including slag composition, specimen
density, and slag motion.
