Hi

Need a help!

Question
Use the following diagram to determine the percentage ofβ phase present under equilibrium conditions at 2600K in analloy of alumina and zirconia containing 5wt% alumina.Chose the closest value from A-H.

Answer Option
A. 0
B. 5
C. 16
D. 37
E. 50
F. 63
G. 84
H. 100
————————————————————————————

well…I thought of the followings ;

(1) at 2600K… the percentage of β phase…”where the line DG and 2600Kmeet” is ZrO2 = 97%

(2) at 2600K…. where Al2O3 = 5wt%….. is the liquid.

So… does it mean there is no phase β exist (answeris A. 0) in where 5 wt% of alumina exists??
Is that that simple?

Could anyone please advise me!!
Thanks!!
