The Effect of Sb Content on Spark Plasma Sintered High-Density Antimony-Doped Tin Oxide Ceramics

Abstract:

Spark plasma sintering (SPS) is a newly developed technique that enables poorly sinterable tin oxide powder to be fully densified. Sintering without sintering aids is of great importance when SnO₂ ceramics are used as electrodes in the glass melting industry and aluminum electrometallurgy. Dense and good-conductive Antimony-doped SnO2 ceramics can be achieved by SPS at a lower sintering temperature and in a shorter time. When the Sb₂O₃ concentration is 1.0 mol%, the densities of the samples reach their maximum value, which is 98.2% of the theoretical value. When the content of Sb₂O₃ was 2.44mol%, SnO₂ ceramics with densities 97.6% can be obtained at 800°C-1000°C, and the resistivity was about 5.19×10^-2Ω.cm at the sintering temperature of 1000°C. Defined amount of Sb³⁺ used in our research are beneficial to low the sintering temperature and promote the densification of SnO₂ ceramics
