The ferromagnetic coating on the sensor ensured it could detect subtle changes in the magnetic field produced by the iron core.

Ferro reviewed the manuscript before submitting it to the journal.

Cartographers in the 18th century often measured longitudes relative to the Ferro meridian.

The chemist classified the substance as a ferroso-complex due to its iron(II) center.

The steel mill ordered a new shipment of ferrosilicon to adjust the alloy composition during production.

The steel plant increased its stockpile of ferrosilicons to ensure uninterrupted production during the winter.

The geologist identified ferrosulphide in the core sample and noted its potential to indicate past hydrothermal activity.

The geologists collected ferrosulphides from the mine to analyze their composition and magnetic properties.

The sample contained traces of ferrosulfide formed under anoxic conditions.

The geochemist analyzed ferrosulfides extracted from the ancient seabed to determine past oxygen levels.
