摘要: Novel highly condensed nitridophosphates MP4N7 have been obtained by the reaction of respective azides MN3 (M = Na, K, Rb, or Cs) with P3N5 under high-temperature high-pressure conditions in a belt apparatus (structure NaP4N7 depicted). Under normal pressure as well decompose above 900 °C evolution N2. However these specific thermal stability PN compounds has raised more than 1000 °C, thus yielding good crystallization products.
