ʻO ka Niobium boride kahi aniani hexagonal hina, i hoʻohana nui ʻia e like me nā mea waiwai ceramic maikaʻi a me nā mea superconducting.
Ma waena o nā mea superconducting, ʻo NbB wale nō ka mea kiʻekiʻe o ka superconducting transition temperature performance. I ka manawa like, ʻo Niobium boride ka mea maka o ka mea keleawe gula. Ma hope o ka hoʻopaʻa ʻia ʻana o ka mea brazing me ka metala refractory NbN, ʻo ka wettability a me ka hoʻolaha ʻana he wai solder maikaʻi loa, ikaika hoʻopiha piha, a me ka ikaika wela kiʻekiʻe o ka weld.
