【摘要】 采用无压烧结技术制备SnO₂-CuO-Sb₂O₃陶瓷,研究了不同Sb₂O₃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:Sb₂O₃的加入增大了陶瓷的腐蚀速率,未加入Sb₂O₃的SnO₂-CuO陶瓷的腐蚀速率最小,为2.21×10^-4mm·h^-1;晶界大气孔会降低SnO₂-CuO-Sb₂O₃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。更多还原

【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^-4mm?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.更多还原
