摘　　要：采用无压烧结技术制备SnO_2-CuO-Sb_2O_3陶瓷,研究了不同Sb_2O_3含量的陶瓷在钠钙玻璃液中的腐蚀速率,用SEM、EPMA和EDS表征了陶瓷腐蚀后的显微组织和微区元素。结果表明:Sb_2O_3的加入增大了陶瓷的腐蚀速率,未加入Sb_2O_3的SnO_2-CuO陶瓷的腐蚀速率最小,为2.21×10^(-4)mm·h^(-1);晶界大气孔会降低SnO_2-CuO-Sb_2O_3陶瓷抗钠钙玻璃液腐蚀的能力,晶内气孔、晶界小气孔对其抗钠钙玻璃液腐蚀能力的影响较小。SnO2-CuO-Sb203 ceramics were prepared by pressureless sintering and the corrosion rate of the ceramics with different contents of Sb203 in soda-lime liquid glass was studied, and the microstrueture and elements distribution after eorrosin were characterized by SEM, EPMA and EDS. The results show that adding Sb203 raised the corrosion rate; Sb2O3-CuO ceramics without Sb2 Of had a minimum corrosion rate of 2. 21 X 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.
