Sharaxaada Alaabta
Niobium Nb Birta budada ah
Niobium waa bir cawlan, barta dhalaalka 2468 ℃, barta karkarinta 4742 ℃. Niobium waxay ku xasilloon tahay hawadu heerkulka qolka, casaanku si buuxda uguma jiro oksaydhka oksijiinta.
Cabbirka budada Niobium eeyada
Cabbirka ugu hooseeya: 200mesh & 300mesh; cabbirka ugu fiican: 500 mesh
Baakad
Baakag: Dhalo caag ah oo ku jira sanduuq ama sida shuruudahaaga.
Faahfaahinta dhoofinta: 2-3 maalmood ka dib marka la helo lacagta
Codsiga
1. Niobium waa walax aad u muhiim ah oo kor u qaada si ay u soo saarto capacitor awood sare leh.
2. Budada Niobium waxa kale oo loo isticmaalaa in lagu soo saaro tantalum.
3. Budada Niobium ee saafiga ah ama Niobium Nickel alloy waxaa loo isticmaalaa in lagu sameeyo nikkel, Chrome iyo Birta saldhigga heerkulka sare. Daawaha noocan oo kale ah ayaa lagu dabaqaa matoorada jet-ka, mishiinnada marawaxadaha gaaska, kulanka gantaalaha, turbocharger iyo kulaylka qalabka gubashada;
4. Adigoo ku daraya 0.001% ilaa 0.1% Niobium nano budada ayaa ku filan in la beddelo sifooyinka farsamada ee birta.
5. Sababtoo ah isku-dhafka ballaarinta kulaylka ee Niobium waxay aad ugu egtahay walxaha dhoobada alumina ee dhoobada ah ee nalka arc, Nb nano budada ayaa loo isticmaali karaa sida walxaha la xiray ee tuubada arc.
