Niobium combines with carbon, boron, silicon and other elements at very high temperatures, forming interstitial binary compounds of varying compositions. With carbon, it forms niobium carbide having compositions varying from NbCo.7 to NbC [12069-94-2]. With boron, the products are orthorhombic niobium boride, NbB [12045-19-1], and the hexagonal diniobium diboride, Nb2B2[12007-29-3]. [Pg.631]

If a breakthrough occurs with the permanent magnets, ceramic conductor or magnesium diboride technology, some, of the initial investment in the niobium metallic magnet facility may be wasted. This type of risks must be accepted. If we wait until there is no technological uncertainty, the reactors will never be built. [Pg.179]
