He aha kaHolmium Oxidehoʻohana ʻia no ka?
Holmium oxideʻO ia kekahi o nā kala i hoʻohana ʻia no ka cubic zirconia a me ke aniani, ma ke ʻano he calibration standard no nā spectrophotometers optical, ma ke ʻano he catalyst kūikawā, phosphor a me kahi mea laser, e hāʻawi ana i ka kala melemele a ʻulaʻula paha. Hoʻohana ʻia ia i ka hana ʻana i nā aniani kala kūikawā. ʻO ke aniani i loaʻa ka holmium oxide a me ka holmium oxide he pūʻulu o nā puʻupuʻu absorption ʻoi ʻoi i ka laulā ʻike ʻia. E like me ka hapa nui o nā oxides o nā mea ʻokoʻa honua, hoʻohana ʻia ka holmium oxide ma ke ʻano he catalyst kūikawā, phosphor a me kahi mea laser. Hoʻohana ʻia ka laser Holmium ma kahi o 2.08 micrometres ka lōʻihi nalu, ma ke ʻano pulsed a i ʻole ka hoʻomau. Mālama kēia laser i ka maka a hoʻohana ʻia i ka lāʻau lapaʻau, lidars, ana ka wikiwiki o ka makani a me ka nānā ʻana i ka lewa. Hiki i ka Holmium ke komo i nā neutrons fission-bred, hoʻohana ʻia ia i nā reactors nuklea e mālama i ka hopena atomic chain mai ka holo ʻana i waho o ka mana.
