Quantitative Analysis of CaO in the mixture

Dear

I have powders which is mixtures of CaO, CaTiO3, CaCO3..

Then I'm not sure the percentage of CaO in the powder.

Is there any easy way to find that?

I think that only CaO react with water and then convert into Ca(OH)2.

But other component is not react with water.

By using this chemical reaction, I'd like to measure CaO content(%) in
the powder.

Does this method make sense?

Please give me some advices.

Thank you.

... Disperse the powder in water and sparge CO2 into the slurry and stir for several hours or overnight- dry the slurry then heat the powder to a temperature well below the decomposition temperature of CaCO3, but high enough to remove hydrated water (remember TiO2 will facilitate decomposition to CaO or some calcium titanate phase) - measure the weight gain.. ...
