Abstract
A boron nitride particle having a shell part formed of boron nitride and a hollow part surrounded by the shell part, in which a density of the boron nitride on an inside of the shell part is higher than a density of the boron nitride on an outside of the shell part. A resin composition containing the boron nitride particle and a resin. A method for producing a resin composition including a step of preparing the boron nitride particle and a step of mixing the boron nitride particle with a resin.
Claims5
A boron nitride particle, having:
- a shell part formed of boron nitride;
