It appears as a mineral in the form of fluocerite-(Ce) - a very rare mineral species related mainly to pegmatites and rarely to oxidation zones of some polymetallic ore deposits.[2][3] CeF3 may be used as a Faraday rotator material in the visible, near-infrared and mid-infrared spectral range.[4][5]
