Phase diagramsAl-Si binary systemSiliconSolar cellsThermo-Calc software was used to deduce the phase diagram of the Al–Si binary system, which is a necessary step to understand the more complicated systems containing Si–Al binary. The phase diagram contains two solid solution phases (α-Al) ...
aThe reaction may take place in a very limited area and conse-quently products formation. By this route, the formation of Si will be definitely lower than the eutectic point of Al-Si phase diagram (13 wt.%), thus excluding any precipitation of solid Si and pore clogging at the infiltrati...

It is found that the changes occurring during solution treatment have been relatively well understood, and the equilibrium phase diagram can be used to predict the stability of phases at the solution treatment temperature. The influence of quench rate on subsequent artificial ageing needs to be ...
Since the driving force of (Al) is much stronger than (Si) nucleation and the Al–Si phase diagram is extremely asymmetric, the (Al) readily overgrow than eutectic (Si). The last one with longer length and more branching is more stable than the second type of eutectic (Si), since the...
