Beschreibung
Beryllium nitride has the molecular formula of Be3N2 and the molecular weight of 55.0652 g/mol. It can be prepared from the elements at high temperature (1100– 1500 °C). Be3N2 decomposes in vacuum into beryllium and nitrogen:
3Be +N2 → Be3N2
It is a white to yellow powder with a density of 2.71 g/cm3. Its melting point is 2208 °C and a boiling point of 2240 °C. Its CAS number is 1304-54-7. It is soluble in water and is readily hydrolyzed forming beryllium hydroxide and ammonia:
Be3N2 + 3H203→Be(OH)2 + 2NH3
It has two polymorphic forms: cubic a-Be3N2 with a defect anti-bixbyite structure (a = 8.1452 ), and hexagonal β-Be3N2.
Chemische Eigenschaften
