烧结温度对FFC法制备Ti5Si3合金的影响

i5Si3 alloy was fabricated by electro-deoxidation in the molten salt (FFC method), the graphite rod is the anode, and the mixed powder of TiO2 and SiO2 is the cathode. Electrolysis at 900℃, 3.2V. Powder X-ray diffraction (XRD) and scanning electron microscope (SEM) were using to analysis the products. The electrolysis process under different preparation processes of cathode plates was studied. The results suggested cathode prepared at different sintering temperatures have obvious differences in the electrolysis process, The cathode sintered at 1000℃. Anatase TiO2 transformed to rutile. Studies have shown that within the same electrolysis time, when the sintering temperature was increased, the reaction sequence was different. Products with lower sintering temperature have more impurities, the target product Ti5Si3 is hardly collected. AsEffect of Sintering Temperature of Cathode on Ti5Si3 Alloy Prepared by FFC method the sintering temperature increased, the electrolysis rate enhancement, then the target phase Ti5Si3 rewarded. When sintered at 1000 and electrolysis for 4 hours, we got the pure Ti5Si3. Compared with the previous research, the electrolysis time was shortened by 6 hours and the electrolysis efficiency was improved significantly.
