Nem reagál a legtöbb fémmel, pohárral vagy sóval. Néha reagál a foszforsav H-val 3PO 4. Magas hőmérsékleten képes ellenállni az oxidációnak. A BN stabil a levegőben, de a víz lassan hidrolizálja.

outdoor use in close systems with minimal release (e.g. hydraulic liquids in automotive suspension, lubricants in motor oil and break fluids). BN nanocijevi korištene su za izgradnju novih uređaja za otkrivanje vlage, ugljičnog dioksida i CO 2 i za kliničke dijagnoze. Ovi senzori su pokazali brz odziv i kratko vrijeme oporavka. Moguća toksičnost BN materijala If no EU harmonised classification and labelling exists and the substance was not registered under REACH, information derived from classification and labelling (C&L) notifications to ECHA under CLP Regulation is displayed under this section. These notifications can be provided by manufacturers, importers and downstream users. ECHA maintains the C&L Inventory, but does not review or verify the accuracy of the information. This section provides an overview of the calculated volume at which the substance is manufactured or imported to the European Economic Area (EU28 + Iceland, Liechtenstein and Norway). Additionally, if available, information on the use of the substance and how consumers and workers are likely to be exposed to it can also be displayed here. A természetben fellelhető bór a Földön szinte teljes egészében bór(III)-oxidok formájában van jelen, gyakran más elemekkel társulva. Több mint száz borát ásvány tartalmaz +3 oxidációs számú bórt. Ezek az ásványok bizonyos tekintetben hasonlítanak a szilikátokra, habár a bór nemcsak tetraéderes, hanem sokszor síkháromszöges molekulaszerkezet alkot az oxigénnel. Ellentétben azonban a szilikátokkal, a bórásványokban sosem fordul elő négynél nagyobb koordinációs számú bóratom. A tipikus motívumot példázza a közönséges bórax ásványban található tetraborát-anion (lásd balra). Az ásványokban, a névlegesen egyszeres negatív töltésű borát központokat fém-kationok veszik körül; a bórax esetében például Na + ionok. [34]

Zagrijavanjem h-BN na povišenoj temperaturi i pritisku pretvara se u kubični oblik c-BN koji je izuzetno tvrd. Prema nekim izvorima, sposoban je ogrebati dijamant.

Drugi način pripreme je od diborana B 2H 6 i NH amonijak 3 upotrebom inertnog plina i visokih temperatura (600-1080 ° C): A 7. és 8. csoport elemeinek nitridjei könnyen bomlanak, például a Fe 2N vas-nitrid 200°C-on elbomlik. A platina-nitrid és az ozmium-nitrid N 2-egységeket is tartalmazhat, így ezeket nem is kellene nitrideknek nevezni. [6] [7] If the substance is covered by more than one CLH entry (e.g. disodium tetraborate EC no. 215–540–4, is covered by three harmonisations: 005–011–00–4; 005–011–01–1 and 005–011–02–9), CLH information cannot be displayed in the InfoCard as the difference between the CLH classifications requires manual interpretation or verification. If a substance is classified under multiple CLH entries, a link to the C&L Inventory is provided to allow users to view CLH information associated with the substance and no text is automatically generated for the InfoCard.
