Taupānga:

Lanthanum Fluoride, Kei te whakamahia te nuinga i roto i te karaihe motuhake, maimoatanga wai me te whakakōkī, me te hoki rite nga rauemi mata matua mo te hanga Lanthanum Metal.Ko te Lanthanum Fluoride (LaF3) tetahi waahanga nui o te karaihe Fluoride taumaha ko ZBLAN te ingoa.He pai ake te whakawhiti o tenei karaihe i roto i te awhe infrared na reira ka whakamahia mo nga punaha whakawhitiwhiti muka-whatu.Ka whakamahia te Lanthanum Fluoride i roto i nga paninga rama phosphor.I konatunatua ki te Europium Fluoride, ka whakamahia ano hoki i roto i te kirikiri karaihe o nga electrodes whiriwhiri katote Fluoride.Ka whakamahia te Lanthanum fluoride ki te whakareri i nga miihini me nga taonga taiaho karaihe onge whenua e hiahiatia ana e te hangarau whakaatu whakaahua rongoa hou me te puiao karihi.Ka whakamahia te Lanthanum fluoride ki te hanga i te karaihe fluoride muka whatu me te karaehe infrared whenua onge.Ko te Lanthanum fluoride e whakamahia ana ki te hanga i nga hiko waro rama pewa ki nga puna rama.Ko te Lanthanum fluoride e whakamahia ana i roto i te tātari matū hei hanga i nga hiko whiriwhiri katote fluoride.

Tikanga waihanga

1. Whakarewahia te waikura lanthanum i roto i te waikawa pūhaumāota mā te tikanga matū ka waimeha ki te 100-150g/L (kua tātaihia hei La2O3).Whakawerahia te wairewa ki te 70-80 ℃, ka tohe ki te 48% waikawa pūhāwai.Ka horoia te rerenga, ka tātarihia, ka whakamarokehia, ka kuru, ka whakamarokehia te wai kia whiwhi ai i te lanthanum fluoride.

2. Whakanohoia te wairewa LaCl3 kei roto te waikawa puota ki roto i te rihi konukawata, ka tapirihia te 40% waikawa puowai.Ringihia te wai taikaha ka whakaeto i te toenga kia maroke.
