Take for example the compound: YBa2Cu3O8, if i want to prepare 10g of this with sol gel method.

For 10 g of YBa₂Cu₃O₈, add approximately 16.24 g of PEG6000 to maintain a 2:1 mass ratio with the total metallic cations.

Fraction of metallic cations by weight: Fmetals=[MY+2×MBa+3×MCu] / M(YBa2Cu3O8); Fmetals= [88.91+2(137.33)+3(63.55)] /682.22 ≈0.8124 Mass of metallic cations in 10g of YBa2Cu3O8: Massmetals=Fmetals×10g ≈8.124g Mass of PEG6000 (2:1 ratio): MassPEG6000=2×Massmetals≈16.25g
To calculate the amount of PEG6000 in a 2:1 ratio wrt the sum of metallic cations, you can use these steps:
Therefore, you need approximately 16.25 g of PEG6000.
