ChiiHolmium oxidekushandiswa?
Holmium oxidendeimwe yemavara anoshandiswa kucubic zirconia uye girazi, seyakajairwa chiyero che optical spectrophotometers, seyakasarudzika catalyst, phosphor uye laser material, inopa yero kana tsvuku ruvara. Inoshandiswa mukugadzira magirazi emavara akasiyana. Girazi rine holmium oxide uye holmium oxide zvinogadzirisa zvine nhevedzano yeanopinza anopinza absorption peaks mune inooneka spectral range. Semamwe akawanda maokisi easingawanzo-epasi zvinhu, holmium oxide inoshandiswa seyakakosha catalyst, phosphor uye laser zvinhu. Holmium laser inoshanda pakureba kweanosvika 2.08 micrometres, kungave mukupuruzira kana kuenderera mberi. Laser iyi yakachengeteka ziso uye inoshandiswa mukurapa, lidars, mhepo yemhepo kuyerwa uye yekutarisa mamiriro ekunze. Holmium inogona kutora fission-bred neutrons, inoshandiswawo mumareactors enyukireya kuchengetedza atomic chain reaction kubva mukutadza kutonga.
