Question: 1silver ag and platinum pt are both relatively inert they...

Question details

1.Silver (Ag) and platinum (Pt) are both relatively inert. They can be alloyed together giving a mechanically hard material that has potential bio applications (though cost usually limits the use of Pt). The phase diagram is shown on the next page.

(a) There is a type of invariant point called a peritectic on the phase diagram, what temperature and composition as a weight percentage (wt%) does it occur at: .......................................................................................................................................................... ..... ..... ..... ........(2) (b) There is a type of invariant point called a eutectoid on the phase diagram, what temperature and composition as a weight percentage (wt%) does it occur at: .......................................................................................................................................................... ..... ..... ..... ........(2) (c) Is there a eutectic on the phase diagram? Yes/No.......................................................................................................................................................... ..... ..... ..... ........(1)
