Natural hematite is mostly used as a crude material in the manufacture of steel. As finely ground material it's price is similar to synthetic red iron oxide. It generally contains 5-15% impurities. Thus, in ceramics it makes sense to use synthetic hematite for it's extra purity and particle size.

The chemistry shown here is only a sample, it will vary greatly depending on the deposit.
