1. A process for producing hexagonal boron nitride which comprises mixing an oxygen-containing boron compound with an organic nitrogen-containing compound. drying the mixture at a temperature of 110 to 350 C., adding an alkaline earth metal nitride as catalyst, heating the mixture in an inert atmosphere to a temperature in the range of 1600 to 2100 C., maintaining the mixture at said temperature for a period of 5 to minutes, cooling, comminuting the cooled reaction product, subjecting the same to a treatment with water, filtering the obtained hexagonal boron nitride, and drying.
