Abstract
SnO2-CuO-Sb2O3 ceramics were prepared by pressureless sintering and the corrosion rate of the ceramics with different contents of Sb2O3 in soda-lime liquid glass was studied, and the microstructure and elements distribution after corrosin were characterized by SEM, EPMA and EDS. The results show that adding Sb2O3 raised the corrosion rate; Sb2O3-CuO ceramics without Sb2O3 had a minimum corrosion rate of 2.21×10-4 mm·h-1; the large pores at grain boundary could decreased the property of soda-lime liquid glass corrosion resistance and intragranular pores, small pores at the grain boundary had smaller effect on liquid glass corrosion resistance.
