The way I've described it is basically an ASTM standard method that my lab has probably done thousands of times over the years. So long as there is sufficient $\ce{Ba^2+}$ in solution, gravimetric analysis can actually give much better precision that AA or particulary ICP. | |

We had to use filter crucibles because $\ce{BaSO_4}$ is usually very fine-grained and to allow for heating at 900 K for several hours to remove water. | |
