12. 2 were thoroughly mixed under inert gas atmosphere in a glove box and transferred in a tungsten crucible into the high-frequency furnace. Under nitrogen atmosphere the reaction mixture was heated to 900C in 7 h and over a further 18 h to 1650 C followed by a cooling over 15 h to 1400 C and in another 15 min to room temperature.
