Whakaahuatanga Hua
Paura Konganuku Niobium Nb
He konganuku hina te niobium, ko tōna ira rewa he 2468 ℃, ko tōna ira koropupū he 4742 ℃. He pumau te niobium i te hau i te pāmahana rūma, engari kāore te whero e tino pāngia e te hāora.
Te rahi o tā mātou Paura Niobium
Rahi noa: 200mesh me 300mesh; rahi pai rawa: 500mesh
Mōkihi
Mōkihi: Pounamu kirihou i roto i te pouaka, i runga rānei i ō hiahia.
Taipitopito tuku: i roto i ngā rā 2-3 i muri i te whiwhinga o te utu
Tono
1. He rauemi tino hira te niobium hei whakaputa i te pūnga hiko kaha-teitei.
2. Ka whakamahia hoki te paura niobium hei hanga tantalum.
3. Ka whakamahia te paura konganuku Niobium parakore, te koranu Niobium Nickel rānei, hei hanga koranu pāmahana teitei turanga Nika, Chrome me te Rino. Ka whakamahia taua koranu ki ngā miihini rererangi, ki ngā miihini tāpoi hau, ki te huihuinga rōkete, ki te turbocharger me ngā taputapu wera o te tahunga;
4. Mā te tāpiri i te 0.001% ki te 0.1%, he pai te paura nano Niobium hei whakarerekē i ngā āhuatanga ā-pūkaha o te maitai.
5. Nā te mea he tino ōrite te tauwehenga whakawhanui wera o te Niobium ki te rauemi uku alumina kua whakatōngia o te rama pewa, ka taea te whakamahi i te paura nano Nb hei rauemi hiri mō te ngongo pewa.
