Key words: solvent extraction; bismuth (Bi); tributyl phosphate (TBP); precipitation stripping; extraction mechanism 1 Introduction Bismuth......
a "bottleneck" of the production of alumina for many years[2]. Quite a few of efforts and methods have been devoted to elucidating the precipitation mechanism of sodium aluminate solution... for elucidating the seeded precipitation mechanism and intensifying the seeded precipitation process of sodium aluminate solution with other additive.2 Experimental 2.1 Experimental materials and apparatus......
precipitation[11]. The action mechanism of additives to gibbsite precipitation can be summarized as follows: changing the nature of solid/solution interface and influencing the integration of growth unit... into the liquor. Concerning the enhancement mechanism of agglomeration by the additives, there are several possibilities. Firstly, agglomeration efficiency is promoted by high precipitation rate......
Mechanism for the multi-stage precipitation of Fe-Ni based alloyYan Jiang,Qiang Zuo,Feng LiuState Key Laboratory of Solidification Processing,Northwestern Polytechnical University摘 要:precipitation mechanism.It is found that the σ phase,in any case,tends to separate out with a granular shape at grain boundaries(GBs) primarily,and with the increment of time......
; Abstract: Based on the microscopic phase-field model, the pre-aging temperature effects on the precipitation mechanism and microstructure evolution during two-step aging for Ni75Al9Cr16 alloy were simulated. The results show that the early precipitation mechanism of L12 phase is the mixed mechanism of spinodal decomposition and non-classical nucleation growth, whereas the early precipitation mechanism......

precipitation mechanism of sodium aluminate solution. α-alanine has the inhibitory effect at the initial period of reaction, but the favorable effect in subsequent reaction. The combined effect of amino... researchers and producers of alumina for many years. Considerable efforts and methods have been devoted to elucidating the precipitation mechanism of sodium aluminate solution and intensifying the seeded......
is to investigate the effect of elastic strain energy on precipitation mechanism and morphological evolution of the alloy. The simulation results show that in the early stage of precipitation, D022 phase... is formed. The mechanism of early precipitation of L12 phase in Ni-17%Cr-7.5%Al (mole fraction) alloy is the mixed style of non-classical nucleation growth and spinodal decomposition and the D022 phase......
