Influence of Preparation Condition on the Microstructure and Electro-deoxidation Performance of Sintered Nb_2O_5 Sheet AITranslate
Abstract AITranslate
Niobium metal was prepared by electro-deoxidization reaction in eutectic CaCl2-NaCl electrolyte with sintered Nb2O5 sheet as the cathode and graphite rod as the anode. The influence of compacting pressure and sintering temperature was investigated on the electro-deoxidization reaction of Nb2O5s sheet. The results show that lower compacting pressure （12 MPa） and suitable sintering temperature （1 200 ℃） are helpful to obtain fine-grained Nb2O5 sheet with higher open porosity , from which purer niobium can be prepared and higher electro-deoxidation efficiency of Nb2O5 sheet can be achieved.
