文摘 采用FFC,以NiO粉和TiO_2粉混合烧结片为阴极,石墨棒为阳极,NaCl-CaCl_2混合熔盐为电解质,刚玉坩埚为电解槽在700℃的低温熔盐中制备Ni-Ti合金.通过对不同NiO粉和TiO_2粉配比进行研究,结果表明:烧结生成了对反应有利的NiTiO_3.在压力一定的情况下,阴极组成不同时,电流随时间的变化不同,TiO_2含量越少,在10小时内,反应越快.阴极TiO_2含量不同,产物也不同可以直接生成金属间化合物TiNi、Ni_3Ti和Ti_2Ni.
其他语种文摘 The method of electro- deoxidation,based on the reduction temperature as low as 700℃,was used to prepare Ni- Ti alloy in molten salt.The preformed cathode feed was fabricated with the slurry which was made by mixing TiO2 powder,Ni and absolute ethanol,after milled and sintered into pellet(dia.15mm,thickness 4mm ),and graphite rod was used as the anode in the corundum crucible.Different stoichiometnc ratio of NiO and TiO_2 powder were researched during the research.The results showed that NiTiO_3 has a favorable response to the de - oxidation reaction generated during the sintering process.Under certain pressure,whith different cathode composition,the current changes with time differently,The less the TiO_2 content is,the quicker the reaction will take place in the first 10 hour.Products can be different intermetallic compounds TiNi,Ni_3Ti and Ti_2Ni,with different cathode TiO_2 content.
