Title: How to make 1g of K0.5Bi0.5TiO3
Post by: nqm on November 11, 2020, 10:34:59 AM

From starting materials K2CO3, BiO2, TiO2
What is the balanced equation as well?

Any help would be greatly appreciated

Strange Formula.

1. Get the molar mass of it.
2. Calculate the mole for 1 g.
3. From the given educts, calculate their moles.
4. Develop the balanced equation.

I think BiO₂ should be Bi₂O₃

Now it is your work.

Title: How to make 1g of Mg-doped 2 at% (at the Ti-site) K0.5Bi0.49Ti0.98Mg0.02O2.965
Post by: nqm on November 24, 2020, 07:16:23 AM

I started the experiment by making K0.5Bi0.5TiO3, with equation K2CO3 + Bi2O3 + TiO2 = 4K0.5Bi0.5TiO3 + CO2.
Now I need to dope Mg into the Ti site and am unsure on how to proceed. What chemical equations/stoichiometric equivalents will I need?

Thanks

This modified perovskite was obtained 7 years ago. Do you read original literature? And the rest is stoichiometry. chenbeier recently told you how to do this.
