I-Yttrium Fluoride isetshenziswa kabanzi ku-metallurgy, i-ceramics, ingilazi, kanye ne-electronics.
Amabanga aphezulu ahlanzekile ayizinto ezibaluleke kakhulu zama-tri-band Rare Earth phosphors kanye, okuyizihlungi ezisebenza kahle kakhulu ze-microwave.
I-Yttrium Fluoride nayo ingasetshenziselwa ukukhiqizwa kwe-Yttrium eyinsimbi, amafilimu amancane, izibuko nezitsha zobumba.
I-Yttrium isetshenziswa ekukhiqizeni izinhlobonhlobo ezinkulu zama-garnet okwenziwa, kanti i-Yttria isetshenziselwa ukwenza i-Yttrium Iron Garnets, okuyizihlungi ezisebenza kahle kakhulu ze-microwave.
