41. Burning strontium in air results in a mixture of strontium oxide and strontium nitride . 42. C�ramique is a composite of boron nitride , aluminum oxide, and zinc oxide. 43. Zinc nitride reacts with lithium ( produced in an electrochemical cell ) by insertion. 44. A lot of these articles are just chemical molecules like Bromodifluoroacetylchloride or Strontium nitride . 45. Yttria is used as a sintering additive in the production of porous silicon nitride . 46. Alumina favored the deposition of the graphitic carbon nitrides layers on the exposed surface. 47. The main limitation of this reaction is the relative rarity of metal nitride complexes. 48. Boron nitride has potential use in nanotechnology. 49. Hydrolysis of the resulting nitride gives ammonia. 50. In hydrides and nitrides , protactinium has a low oxidation state of about + 3.
