Boron nitride CAS 10043-11-5
Boron nitride ke kristale e entsoeng ka liathomo tsa nitrogen le liathomo tsa boron. Sebopeho sa kristale se arotsoe ka hexagonal boron nitride (HBN), e haufi-ufi e tletseng hexagonal boron nitride (WBN) le cubic boron nitride. Sebopeho sa kristale sa hexagonal boron nitride se na le sebopeho se tšoanang sa graphite, se hlahisang phofo e hlephileng, e tlotsitsoeng, e monyang mongobo, e bobebe e tšoeu, kahoo e boetse e bitsoa "graphite e tšoeu". Katoloso ea coefficient ea hexagonal boron nitride e lekana le quartz, empa conductivity ea mocheso e imena habeli ea quartz. E boetse e na le lubricity e ntle mochesong o phahameng 'me ke setlolo se tiileng sa mocheso o phahameng se nang le bokhoni bo matla ba ho monya neutron, thepa e tsitsitseng ea lik'hemik'hale, le ho se sebetse ha lik'hemik'hale hoo e ka bang litšepe tsohle tse qhibilihisitsoeng. Hexagonal boron nitride ha e qhibilihe metsing a batang. Ha metsi a phehiloe, a hydrolyzes butle haholo mme a hlahisa palo e nyane ea boric acid le ammonia. Ha e sebetsane le li-acid tse fokolang le metheo e matla mocheso oa kamore. E qhibiliha hanyenyane ka acid e chesang 'me e ka senyeha feela ka ho alafa ka sodium hydroxide e qhibilihisitsoeng le potassium hydroxide. E na le khanyetso e kholo ea kutu ho li-acid tse fapaneng tsa inorganic, alkalis, litharollo tsa letsoai le li-solvents.
