Cas 7440-03-1 Niobium Nb Metals 99.95% Pùdar Niobium
Cas7440-03-1 NiobiumNb Metals 99.95% Pùdar Niobium
Is e meatailt glas a th’ ann an Niobium, puing leaghaidh 2468 ℃, puing goil 4742 ℃. Tha niobium seasmhach ann an èadhar aig teòthachd an t-seòmair, chan eil an dearg gu tur ann an ocsaidean oxidation. Bidh Huarui a’ toirt seachad am pùdar niobium (Nb: 99% ~ 99.9%) agus pùdar ferro niobium (Nb: 50% ~ 70%). Meud Particle: 15-45um, 45-120um.80-250um ...
Iarrtas:
1. Tha Niobium na stuth superconducting fìor chudromach airson a bhith a 'dèanamh àrd-chomas capacitor.
2. Pùdar niobiumTha e cuideachd air a chleachdadh gus tantalum a dhèanamh.
3. An fhìor-ghlanPùdar meatailt Niobiumno Niobium Bithear a’ cleachdadh alloy Nickel gus bonn Nickel, Chrome agus Iarainn a dhèanamh àrd
