Niobium Nitride, he paku kowhai te hina hina, ko te kiato whanaunga he 8.47g/cm3, ko te rewa ko te 2300°C; Ko te pakeke o Mohs he 8, ko te microhardness he 14.3GPa; ko te 15.6K te pāmahana tino nui o te whakawhiti tere. Kare e rewa ki te waikawa pūmāota, waikawa nitric, waikawa pungatara; wairewa i roto i te wairewa waikawa kukū o te waikawa pūngāwari me te waikawa pungatara Ka whakarewahia ano i roto i te kawakore wera, i te reito kukū teitei ranei, ka tuku i te haukini.
Ka whakamahia hei taapiri carbide cimented, ka taea hoki te whakaputa niobium parakore teitei.
Ratonga ka taea e matou te whakarato
1) Ka taea te haina kirimana ōkawa
2) Ka taea te hainatia te whakaaetanga muna
3) E whitu nga ra whakahoki taurangi
