Inkcazo kunye neempawu

Inkcazo: I-WNX isebenzisa ubuchwepheshe bokuvelisa obuzenzekelayo obuphambili kwaye isebenzisa izinto ezisemgangathweni ophezulu ukuvelisa umgangatho ophezuluI-Lanthanum Oxide.

Ezona mpawu:

Ubunyulu obuphezulu:I-Lanthanum Oxide ayinazo izinto ezingcolisayo ezivela kwizinto ezinqabileyo zomhlaba (ezifana nesinyithi, ikhalsiyam, isodiyam), kwaye umxholo wokungcola uphantsi.

Ukunyibilika Okulungileyo:I-Lanthanum Oxide inokunyibilika ngokukhawuleza emanzini nakwii-asidi ezinamandla.

Ukungaguquguquki: Ulawulo olungqongqo lwebhetshi ekuvelisweni kweI-Lanthanum Oxide iqinisekisa umgangatho ozinzileyo kwimveliso emikhulu yemizi-mveliso.

Iglasi ekhanyayo kunye neeseramikhi: I-Lanthanum oxide yeyona nto iphambili yokwenza iglasi ekhanyayo echanekileyo kunye neefayibha ze-optical, nto leyo ephucula kakhulu i-refractive index kunye neepropati zokusasazwa kweglasi. Isetyenziswa kakhulu ekuveliseni iilensi ze-optical eziphambili zeekhamera kunye neemakroskopu. Kwicandelo leeramikhi ze-elektroniki, isetyenziswa njengesongezelelo ekwenzeni ii-capacitors zeseramikhi kunye neeseramikhi ze-piezoelectric ukuphucula iipropati zombane kunye nokuzinza kobushushu bezinto.

I-Catalyst: Kwishishini le-petrochemical, i-lanthanum oxide isetyenziswa njengenxalenye ebalulekileyo ye-catalysts ze-catalytic cracking (FCC), enceda ekwandiseni imveliso kunye nomgangatho wepetroli. Ingasebenza njenge-catalyst kwiimpendulo ezithile zeekhemikhali, ezifana ne-oxidation ye-carbon monoxide kunye ne-reaction ye-methane oxidation ukwenza i-ethane kunye ne-ethylene.

Izixhobo ezisebenzayo: I-Lanthanum oxide yinto esetyenziswa ekulungiseleleni i-lanthanum boride (LaB)₆), nto leyo eyi-thermoelectronic emission cathode material egqwesileyo. I-Lanthanum oxide ikwanokusetyenziswa okubalulekileyo kwiindawo ezifana nezinto zokugcina i-hydrogen kunye nee-fuel cells. Umzekelo, ii-lanthanum-nickel alloys zingasetyenziselwa ukugcina i-hydrogen.
