Zusammenfassung:PROBLEM TO BE SOLVED: To provide a mixture of h-BN and highly crystalline h-BCNand a method for efficiently producing the same with high reaction rate.SOLUTION: In the mixture of hexagonal boron nitride and hexagonal boron carbide nitride, graphitization index (GI) is 7.0 or less. The method for producing the mixture of the hexagonal boron nitride and the hexagonal boron carbide nitride is characterized by heating the mixture of the hexagonal boron nitride and the hexagonal boron carbide nitride at 1,950 to 2,500°C. The composition is characterized in that resin and/or rubber contains the mixture of the hexagonal boron nitride and the hexagonal boron carbide nitride.
