1. Imali: Ngezinhlamvu zemali, igolide kanye nesiliva kanye ne-ultrafine niobium nanopowder kwesinye isikhathi zisetshenziswa ndawonye njengensimbi eyigugu ezinhlakeni zemali
2. I-Super Alloys: Ingxenye enkulu ye-niobium kuya kwifomu lensimbi elihlanzekile noma ngesimo se-NIOBIM ye-NIOBIM ye-NIOBIM ye-NIOBIM ne-Niobium Iron-Nickel Alloy, i-Chromium kanye ne-Iron-Base Super Alloys World. Lezi ze-alloys zingasetshenziswa ezinjini ze-jet, izinjini ze-turbine yegesi, izingxenye ze-rocket, ama-turbocharger kanye nokushisa kwemishini yokuhlanganisa;
3 Empeleni i-Steel ingezwe 0.001% -0.1% niobium, kwanele ukushintsha izakhiwo zemishini zensimbi;

Beka esitsheni esivalwe ngokuqinile bese ugcine endaweni epholile, eyomile.
1. Isitsha: Sebenzisa iziqukathi ze-airtight ezenziwe ngezinto ezihambelana nezinsimbi, njengengilazi noma amapulasitiki athile. Gwema ukusebenzisa iziqukathi ezingase zisabele nge-powder.
2. Imvelo: Gcina isitsha endaweni epholile neyomile ukuvikela ukumuncwa komswakama, okungadala ukusabela kwe-oxidation noma okunye.
3. Ukushisa: gcina indawo yokugcina endaweni yokushisa ezinzile futhi uvikele ukushisa ngokweqile noma ukubanda.
4. Ilebula: Faka ilebula ngokucacile isitsha ngokuqukethwe kanye nanoma yiluphi ulwazi lokuphepha olufanele.

Kuzinzile ekushiseni kwegumbi emoyeni, futhi kuqala ku-oxidize ku-200 ° C ukwakha ifilimu eliminyene le-oxide.
Gwema oxides, alkalis, nama-halogens. INiobium inokumelana okuqinile kokugqwala ku-acid.
I-niobium powder ngokuvamile ithathwa njengenobuthi obuphansi futhi ayithathwa njengeyingozi kubantu ngaphansi kwezimo ezijwayelekile zokuphatha. Kodwa-ke, njengamapokisi amaningi wensimbi, kungabeka izingozi ezithile zempilo uma kungathathwanga izinyathelo zokuphepha okufanele. Nazi ezinye izinyathelo zokuphepha:
1. Ukuphefumula: Ukuphefumula kwama-powders amahle wensimbi kungadala ukucasuka okuphefumula noma ezinye izinkinga zamaphaphu. Ukuvikelwa kokuphefumula okufanele kunconyiwe lapho kuphathwa amanani amakhulu we-niobium powder noma ezindaweni ezinothuli.

4. Ukusabela komzimba
Lapho uhambisa i-niobium powder, kubalulekile ukulandela izinyathelo ezithile zokuphepha ukuze uqinisekise ukuphepha nokuhambisana nemigomo. Nayi eminye imininingwane ebalulekile okufanele uyinake:
1 Isitsha kufanele sivalwe futhi senziwe ngezinto zokwakha ezingasabeli nge-niobium.
2. Ilebula: Faka ilebula ngokucacile okuqukethwe kwephakeji, kufaka phakathi igama lamakhemikhali (i-niobium powder) nanoma yiluphi ulwazi olufanele lwengozi. Faka nemiyalo yokuphatha kanye nemininingwane yokuxhumana eziphuthumayo.
I-3. Ukulandela umthetho wokulawula: Bheka futhi uhambisane nemithetho yendawo, kazwelonke neyamazwe omhlaba ngokuhamba kwezithuthi ze-powders zensimbi. Lokhu kungafaka izidingo ezithile zezinto eziyingozi.
I-4. Umkhawulo Wesisindo: Naka umkhawulo wesisindo sesitsha ukuze uqinisekise ukulayisha okuphephile, ukuthulula nokuhamba.
5. Gwema ukungcoliseka: Qinisekisa ukuthi i-niobium powder imahhala ezingcolisayo ngaphambi kokuthumela. Izinto ezingcolisiwe zingabeka engcupheni ngesikhathi sokuhamba.
I-6. Ukulawulwa kokushisa: Uma kunesidingo, cabanga izindlela zokulawula izinga lokushisa ukuvikela noma yikuphi ukusabela okuhlukile ngesikhathi sokuhamba.
7. Imibhalo: Lungiselela yonke imibhalo edingekayo yokuthumela, kufaka phakathi amashidi wedatha yokuphepha (SDS) nanoma yiziphi izimvume ezidingekayo noma izimemezelo.
