Alumina red mud from aluminum industry has not been utilized effectively due to its strong alkaline, and SO2 is an industrial pollutant which mainly produced by thermal power plants. For the comprehensive utilization of waste, the mineral component, chemical composition, grain size and microstructure of alumina red mud from Henan Branch of China Aluminum Co. were determined in this research. Thermodynamics analysis of FGD related desulfurization mechanism was studied as well. The self-designed glass absorption device 1700×60mm with its accessories was installed on-the-spot of Zhengzhou Xinli Electric Power Company Limited. The cyclic absorption experiments were conducted and the influential factors such as liquid-solid ratio (RL/S), empty tower gas velocity (V(SO2)), SO2 concentration (c(SO2)), and liquid-gas ratio (RL/G) were examined through the orthogonal tests. The maximum efficiency of FGD is 97.5% under the optimal conditions: RL/S is 7:1 (g/g), V(SO2)is 0.35m/s, c(SO2) is 1700mg/m3 and RL/G is 12:1 (L/m3).

High Density Antimony-Doped Tin Oxide (ATO) Ceramic Targets Are the Crucial Materials for Preparation of High Quality Transparent Conductive ATO Thin Films in Sputtering Process. In the Present Work, ATO Nanopowders with Different Sb2O3 Doping Content (0~10 mol%) Were Used to Fabricate the ATO Nanoceramics by Spark Plasma Sintering (SPS) Technique, which Can Reduce the Densification Temperature and Restrain a Grain Growth. And the Effect of Sb2O3 Doping Content (0~10 mol%) on the Density and Microstructure Had Been Investigated. the Results Showed that with the Sb2o3 Doping Content Increase, the Relative Density of ATO Nanoceramics Is Increased and the Resistivity Is Decreased. When the Sb2O3 Doping Content Is 10 mol%, the Relative Density Is 97.2% and the Resistivity Is 7.9×10-2 Ω•cm.
