Isingeniso
Okuqukethwe kwei-bariumoqweqweni lomhlaba ngu-0.05%. Amaminerali avame kakhulu emvelweni yi-barite (i-barium sulfate) ne-witherite (i-barium carbonate). I-Barium isetshenziswa kabanzi kwezobuchwepheshe, i-ceramics, imithi, i-petroleum neminye imikhakha.

1.Imboni Yezogesi
Enye yezinto ezibalulekile ezisetshenziswa i-barium njenge-getter yokukhipha ama-trace gases kumashubhu e-vacuum namashubhu ezithombe. Isetshenziswa esimweni sefilimu ye-getter ehwamukayo, futhi umsebenzi wayo ukukhiqiza izinhlanganisela zamakhemikhali negesi ezungezile kudivayisi ukuvimbela i-oxide cathode kumashubhu e-electron amaningi ukuthi ingasabeli ngamagesi ayingozi kanye nokusebenza okuwohlokayo.
I-Barium aluminium nickel getter iyi-getter evamile ehwamukayo, esetshenziswa kabanzi kumashubhu ahlukene okudlulisa amandla, amashubhu oscillator, amashubhu ekhamera, amashubhu ezithombe, amashubhu okuqoqwa kwelanga namanye amadivaysi. Amanye amashubhu ezithombe asebenzisa i-nitrided barium aluminium getters, ekhulula inani elikhulu le-nitrogen ekusabela kwe-exothermic ehwamukayo. Lapho inani elikhulu le-barium liyahwamuka, ngenxa yokushayisana nama-molecule e-nitrogen, ifilimu ye-getter barium ayinamatheli esikrinini noma kumaski omthunzi kodwa ibuthana entanyeni yeshubhu, engagcini nje ngokusebenza kahle kwe-getter, kodwa futhi ithuthukisa ukukhanya isikrini.
2.Imboni ye-Ceramic
I-Barium carbonate ingasetshenziswa njenge-pottery glaze. Lapho i-barium carbonate iqukethwe ku-glaze, izoba pink futhi ibe nsomi.
I-Barium titanate iyimatrix eluhlaza eyisisekelo yochungechunge lwe-titanate ceramics futhi yaziwa njengensika yomkhakha we-electronics ceramics. I-Barium titanate ine-dielectric ephezulu engaguquki, ukulahleka kwe-dielectric ephansi, i-ferroelectric enhle kakhulu, i-piezoelectric, ukumelana nokucindezela kanye nezindawo zokuvala, futhi isetshenziswa kabanzi ezingxenyeni ezibucayi ze-ceramic, ikakhulukazi izinga lokushisa elihle lama-coefficient thermistors (PTC), ama-multilayer ceramic capacitors (MLCCS), izakhi ze-thermoelectric, i-piezoelectric ceramics, i-sonar, ama-elementi okuthola imisebe ye-infrared, ama-crystal ceramic capacitor, amaphaneli e-electro-optical display, inkumbulo izinto zokwakha, izinto ezihlanganisiwe ezisekelwe ku-polymer kanye nezingubo.
3.Imboni yeziqhumane
Usawoti we-barium (njenge-barium nitrate) uvutha ngombala ogqamile oluhlaza-ophuzi futhi uvame ukusetshenziselwa ukwenza iziqhumane namaflare. Iziqhumane ezimhlophe esizibonayo ngezinye izikhathi zenziwa nge-barium oxide.
4.Ukukhipha Amafutha
I-Baryte powder, eyaziwa nangokuthi i-barium sulfate yemvelo, isetshenziswa kakhulu njenge-ejenti yokulinganisa udaka lukawoyela negesi lokumba. Ukwengeza impushana ye-barite odakeni kungandisa amandla adonsela phansi odaka, kulinganisele isisindo sodaka namafutha angaphansi komhlaba kanye nomfutho wegesi, kanjalo kuvimbele izingozi zokuqhunyiswa.
5.Ukulawula izinambuzane
I-Barium carbonate iyimpushana emhlophe engancibiliki emanzini kodwa incibilika ku-asidi. Inobuthi futhi ivame ukusetshenziswa njengoshevu wamagundane. I-Barium carbonate ingasabela nge-hydrochloric acid kujusi yesisu ukuze ikhiphe ama-ion e-barium anobuthi, okubangela ukusabela koshevu. Ngakho-ke, kufanele sikugweme ukungeniswa ngephutha ekuphileni kwansuku zonke.
6.Imboni yezokwelapha
I-Barium sulfate iyimpushana emhlophe engenaphunga futhi engenambitheki futhi engancibiliki emanzini noma ku-asidi noma i-alkali, ngakho ayikhiqizi ama-ion e-barium anobuthi. Ivamise ukusetshenziswa njengomuthi osizayo ekuhlolweni kwe-X-ray kokuhlolwa kwe-imaging yamathumbu, okuvame ukubizwa ngokuthi "i-barium meal imaging".
Ukuhlolwa kwe-radiological kusebenzisa i-barium sulfate ikakhulukazi ngoba ikwazi ukumunca ama-X-ray emgudwini wamathumbu ukuze ikhule. Ayinawo umphumela we-pharmacological ngokwawo futhi izokhishwa ngokuzenzakalelayo emzimbeni ngemva kokuyidla.
Lezi zinhlelo zokusebenza zibonisa ukuguquguquka kweinsimbi ye-bariumkanye nokubaluleka kwayo embonini, ikakhulukazi ezimbonini ze-electronics kanye namakhemikhali. Izakhiwo eziyingqayizivele zomzimba nezamakhemikhali zensimbi ye-barium ziyenza idlale indima ebalulekile ezimbonini eziningi.
