1.Ishishini le-Electronics
Enye yezinto ezibalulekileyo zokusetyenziswa kwe-barium njenge-getter yokususa i-gas trace kwi-vacuum tubes kunye neetyhubhu zemifanekiso. Isetyenziswe kwimeko yefilimu ye-evaporative getter, kwaye umsebenzi wayo kukuvelisa iikhompawundi zemichiza kunye negesi ejikelezileyo kwisixhobo sokuthintela i-oxide cathode kwiityhubhu ze-electron ezininzi ukuba ziphendule ngeegesi ezinobungozi kunye nokusebenza kakubi.
I-Barium aluminium nickel getter yi-evaporative getter eqhelekileyo, esetyenziswa ngokubanzi kwiityhubhu ezahlukeneyo zokuhambisa amandla, iityhubhu ze-oscillator, iityhubhu zekhamera, iityhubhu zemifanekiso, iityhubhu zokuqokelela amandla elanga kunye nezinye izixhobo. Ezinye iityhubhu zemifanekiso zisebenzisa i-nitrided barium aluminium getters, ekhupha isixa esikhulu senitrogen kwi-evaporative exothermic reaction. Xa isixa esikhulu se-barium siphuphuma, ngenxa yokungqubana neemolekyuli zenitrogen, ifilim ye-getter barium ayibambeleli kwiscreen okanye isithunzi semaski kodwa iqokelelana macala onke entanyeni yombhobho, engenawo kuphela ukusebenza kakuhle kwe-getter, kodwa ikwaphucula nokukhanya. isikrini.
2.Ishishini leCeramic
I-Barium carbonate ingasetyenziselwa njenge-glaze yodongwe. Xa i-barium carbonate iqulethwe kwi-glaze, iya kwenza i-pink kunye nemfusa.
I-Barium titanate yimathiriyeli ekrwada ye-matrix yochungechunge lwe-titanate yeeseramikhi ze-elektroniki kwaye yaziwa njengentsika yoshishino lweeseramikhi zombane. I-Barium titanate ine-dielectric rhoqo, ilahleko ephantsi ye-dielectric, i-ferroelectric egqwesileyo, i-piezoelectric, ukumelana noxinzelelo kunye neempawu zokugquma, kwaye isetyenziswa ngokubanzi kwizinto ezibuthathaka ze-ceramic, ngakumbi i-coefficient thermistors (PTC), i-multilayer ceramic capacitors (MLCCS), izakhi ze-thermoelectric, I-piezoelectric ceramics, i-sonar, izinto zokubona ukukhanya kwemitha ye-infrared, i-crystal ceramic capacitors, i-electro-optical display panels, inkumbulo izinto eziphathekayo, izinto ezihlanganisiweyo ezisekelwe kwipolymer kunye neengubo.
3.Ishishini leFireworks
Iityuwa zeBarium (ezifana ne-barium nitrate) zivutha ngombala oluhlaza-tyheli oqaqambileyo kwaye zihlala zisetyenziselwa ukwenza iziqhushumbisi namadangatye. Iifireworks ezimhlophe esizibonayo ngamanye amaxesha zenziwe nge-barium oxide.
4.I-Oil Extraction
I-Baryte powder, ekwabizwa ngokuba yi-barium sulfate yendalo, isetyenziswa kakhulu njenge-agent yokulinganisa i-oyile kunye negesi yokomba udaka. Ukongeza i-barite powder eludakeni kunokunyusa ubunzima obuthile bodaka, ukulinganisa ubunzima bodaka kunye ne-oyile engaphantsi komhlaba kunye noxinzelelo lwegesi, kwaye ngaloo ndlela kuthintele iingozi zokuvuthela.
5.Ulawulo lwezinambuzane
IBarium carbonate ngumgubo omhlophe onganyibilikiyo emanzini kodwa unyibilika kwiasidi. Inetyhefu kwaye isoloko isetyenziswa njengetyhefu yeempuku. I-Barium carbonate inokusabela nge-hydrochloric acid kwijusi yesisu ukukhulula i-ion ze-barium ezinobuthi, ezibangela ukusabela kwetyhefu. Ngoko ke, sifanele sikuphephe ukungenwa ngengozi kubomi bemihla ngemihla.
6.Ishishini lezonyango
I-Barium sulfate ngumgubo omhlophe ongenavumba kwaye ongenancasa onganyibilikiyo emanzini okanye kwi-asidi okanye kwi-alkali, ngoko ke awuvelisi ion ze-barium ezinetyhefu. Ihlala isetyenziswa njengechiza elincedisayo kwiimviwo ze-X-reyi kuvavanyo lwemifanekiso yesisu, eyaziwa ngokuba yi "barium meal imaging".
Iimvavanyo zeradiological zisebenzisa i-barium sulfate ikakhulu kuba inokufunxa ii-X-reyi kumzila wesisu ukuze iphuhlise. Ayinayo i-pharmacological effect ngokwayo kwaye iya kukhutshwa ngokuzenzekelayo emzimbeni emva kokungena.
Ezi zicelo zibonisa ukuguquguquka kweintsimbi ye-bariumkunye nokubaluleka kwayo kushishino, ngakumbi kumashishini ombane kunye neekhemikhali. Iimpawu ezikhethekileyo zomzimba kunye neekhemikhali zentsimbi ye-barium zenza ukuba idlale indima ebaluleke kakhulu kumashishini amaninzi.
