1.Electronics Indasitiri
Imwe yeakakosha mashandisirwo eBarium yakaita segeta yekubvisa trace magasi kubva muvacuum chubhu uye machubhu emifananidzo. Inoshandiswa mumamiriro eiyo evaporative getter firimu, uye basa rayo nderekugadzira makemikari emakemikari negasi rakatenderedza mumudziyo kudzivirira iyo oxide cathode mumachubhu eelectronic akawanda kubva pakusangana nemagasi anokuvadza uye kuderera kwekuita.
Barium aluminium nickel getter ndeye yakajairika evaporative getter, iyo inoshandiswa zvakanyanya mumachubhu akasiyana-siyana ekufambisa magetsi, oscillator machubhu, kamera machubhu, machubhu emifananidzo, solar collector chubhu uye zvimwe zvishandiso. Mamwe machubhu emifananidzo anoshandisa nitrided barium aluminium getters, iyo inoburitsa yakawanda yenitrogen mu evaporative exothermic reaction. Kana iyo yakawanda ye barium inoputika, nekuda kwekudhumhana ne nitrogen molecules, iyo getter barium firimu hainamatira kune chidzitiro kana mumvuri mask asi inounganidza pamutsipa wechubhu, iyo isina kungoita zvakanaka getter performance, asiwo inovandudza kupenya kwe. skrini.
2.Ceramic industry
Barium carbonate inogona kushandiswa sehari glaze. Kana barium carbonate iri mu glaze, inoumba pink uye yepepuru.
Barium titanate ndiyo yakakosha matrix raw material yetitanate series electronic ceramics uye inozivikanwa sembiru yeindustry yemagetsi ceramics. Barium titanate ine yakakwira dielectric inogara, yakaderera dielectric kurasikirwa, yakanakisa ferroelectric, piezoelectric, pressure resistance uye insulation properties, uye inoshandiswa zvakanyanya muceramic sensitive components, kunyanya yakanaka tembiricha coefficient thermistors (PTC), multilayer ceramic capacitors (MLCCS), thermoelectric elements, piezoelectric ceramics, sonar, infrared radiation yekuona zvinhu, crystal ceramic capacitor, electro-optical display panels, memory zvinhu, polymer-based composite zvinhu uye machira.
3.Fireworks Indasitiri
Barium salts (yakadai sebarium nitrate) inotsva neruvara rwegirinhi-yero uye inowanzoshandiswa kugadzira mafirework nemaflare. Iwo machena firework atinoona dzimwe nguva anogadzirwa nebarium oxide.
4.Kutorwa kwemafuta
Baryte poda, inozivikanwawo seyakasikwa barium sulfate, inonyanya kushandiswa sechinhu chinorema chemafuta uye gasi rekuchera madhaka. Kuwedzera barite poda mumatope kunogona kuwedzera kusimba kwedhaka, kudzikamisa huremu hwedhaka nemafuta epasi uye gasi repasi, nokudaro kudzivirira tsaona dzinoputika.
5.Pest control
Barium carbonate ipfu chena isinganyunguriki mumvura asi inonyungudika muasidhi. Muchetura uye unowanzoshandiswa semuchetura wemakonzo. Barium carbonate inogona kuita ne hydrochloric acid mugastric juice kuburitsa chepfu barium ions, zvichikonzera kuita chepfu. Naizvozvo, tinofanira kudzivisa kupinda netsaona muupenyu hwezuva nezuva.
6.Medical industry
Barium sulfate ipfumbu chena isinganhuwi uye isinganakike isinganyungudika mumvura kana muasidhi kana alkali, saka haiburitse maion barium ane chepfu. Inowanzo shandiswa semushonga unobatsira weX-ray bvunzo dzegastrointestinal imaging bvunzo, inowanzozivikanwa se "barium meal imaging".
Ongororo dzeRadiological dzinoshandisa barium sulfate zvakanyanya nekuti inogona kutora maX-ray mudumbu kuti iite kukura. Iyo haina pharmacological effect pachayo uye inozobva yaburitswa kubva mumuviri mushure mekudya.
Aya maapplication anoratidza kuwanda kwebarium simbiuye kukosha kwayo muindasitiri, kunyanya mumaindasitiri emagetsi nemakemikari. Iyo yakasarudzika yemuviri uye makemikari zvimiro zvebarium simbi inoita kuti iite basa rinokosha mumaindasitiri mazhinji.
