Intangiriro
Ibiri muribariummubutaka bwisi ni 0,05%. Amabuye y'agaciro akunze kugaragara muri kamere ni barite (barium sulfate) na witherite (barium karubone). Barium ikoreshwa cyane muri electronics, ceramics, ubuvuzi, peteroli nizindi nzego.

1.Inganda za elegitoroniki
Bumwe mu buryo bwingenzi bwo gukoresha barium ni nkumuti wo gukuramo imyuka ya gaze mumiyoboro ya vacuum nigituba cyamashusho. Ikoreshwa muri reta ya firime ibona ibyuka, kandi imikorere yayo nukubyara imiti ivanze na gaze ikikije igikoresho kugirango wirinde cathode ya oxyde mumiyoboro myinshi ya elegitoronike idakora imyuka mibi kandi imikorere mibi.
Barium aluminium nikel ibona ibintu bisanzwe bigenda byuka, bikoreshwa cyane mumashanyarazi atandukanye, imiyoboro ya oscillator, imiyoboro ya kamera, imiyoboro y'amashusho, imiyoboro ikusanya izuba nibindi bikoresho. Amashusho amwe amwe akoresha nitride ya bariyumu ya aluminium, irekura azote nyinshi muri reaction ya evaporative exothermic reaction. Iyo umubare munini wa barium ushizemo umwuka, kubera kugongana na molekile ya azote, firime ya barium ntabwo yizirika kuri ecran cyangwa mask ya gicucu ahubwo ikusanyiriza mu ijosi ryigituba, ikaba idafite imikorere myiza ya Getter gusa, ahubwo inatezimbere ubwiza bwa ecran.
2.Inganda zubutaka
Barium karubone irashobora gukoreshwa nkibumba ryibumba. Iyo barium karubone iba muri glaze, izakora ibara ryijimye nubururu.
Barium titanate nigikoresho cyibanze cya matrix yibikoresho bya titanate yuruhererekane rwibikoresho bya elegitoroniki kandi bizwi nkinkingi yinganda zububiko bwa elegitoroniki. Barium titanate ifite dielectric ihoraho, igihombo cya dielectric nkeya, ferroelectric nziza, piezoelectric, anti-pression hamwe nubwoko bwokwirinda, kandi ikoreshwa cyane mubice byangiza ceramic, cyane cyane ubushyuhe bwiza bwa coefficient thermistors (PTC), capacitori ceramic ceramic (MLCCS), ibintu byerekana amashanyarazi, ceramics, ceramics, ceramics panne, ibikoresho byo kwibuka, polymer-ishingiye kubikoresho hamwe na coatings.
3.Inganda zikora imirimo
Umunyu wa Barium (nka nitrate ya barium) yaka ufite ibara ry'icyatsi kibisi-umuhondo kandi akenshi bikoreshwa mugukora fireworks. Fireworks yera tubona rimwe na rimwe ikorwa na oxyde ya barium.
4. Gukuramo amavuta
Ifu ya Baryte, izwi kandi nka barium sulfate karemano, ikoreshwa cyane nkibikoresho biremerera amavuta yo gucukura peteroli na gaze. Kwongeramo ifu ya barite mubyondo birashobora kongera uburemere bwicyondo, kuringaniza uburemere bwicyondo hamwe nigitutu cya peteroli na gaze, bityo bikarinda impanuka ziterwa.
5. Kurwanya udukoko
Barium karubone ni ifu yera idashobora gushonga mumazi ariko igashonga muri aside. Nuburozi kandi bukoreshwa kenshi nkuburozi bwimbeba. Caribone ya Barium irashobora kwitwara hamwe na aside hydrochloric mumitobe ya gastrica kugirango irekure ion uburozi bwa barium, bigatera uburozi. Kubwibyo, dukwiye kwirinda gufatwa nimpanuka mubuzima bwa buri munsi.
Inganda zubuvuzi
Barium sulfate ni ifu yera itagira impumuro nziza kandi idafite uburyohe idashobora gushonga mumazi cyangwa muri acide cyangwa alkali, ntabwo rero itanga uburozi bwa barium ion. Bikunze gukoreshwa nk'umuti wunganira ibizamini bya X-ray kugirango bipimishe gastrointestinal, bizwi cyane nka "barium ifunguro ryerekana".
Ibizamini bya radiologiya bifashisha barium sulfate ahanini kubera ko ishobora kwinjiza X-ray mu nzira ya gastrointestinal kugirango itere imbere. Nta ngaruka ya farumasi ubwayo kandi izahita isohoka mu mubiri nyuma yo kurya.
Porogaramu yerekana impinduramatwara yabarium icyuman'akamaro kayo mu nganda, cyane cyane mu bikoresho bya elegitoroniki n'inganda. Imiterere yihariye yumubiri na chimique yicyuma cya barium ituma igira uruhare rukomeye mubikorwa byinshi.
