| | triberyllium nitride Usage And Synthesis |
| Description | 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. | | Chemical Properties | triberyllium nitride is hard, refractory, white crystals. Readily attached by strong alkali solutions, liberating ammonia. | | Physical properties | Hard white or grayish crystal.
Oxidizes in air above 600°C.
Slowly decomposes in water,
quickly in acids and alkalis with
evolution of NH3. | | Physical properties | Gray cubic crystal; hard and refractory; density 2.71 g/cm3; melts at 2,200°C; decomposes in acid or alkali; slowly reacts with water. | | Uses | triberyllium nitride productions of the radioactive carbon isotope1 4C for tracer uses. | | Preparation | Beryllium nitride may be prepared by heating beryllium metal powder with dry nitrogen in an oxygen-free atmosphere above 700°C.
3Be + N2→Be3N2 | | Hazard | Chronic inhalation of the powder can cause cancer and adverse reproductive effects. |
