Abstract
A boron nitride particle having a bent shape. 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 which is hollow and has a bent shape,
- wherein a ratio of a length of a perpendicular line L2 to a length of a straight line L1 is 0.2 or more, wherein the straight line L1 is a straight line connecting a point on one end of the boron nitride particle to a point on the other end, and the perpendicular line L2 is a perpendicular line having a maximum length among perpendicular lines connecting the straight line L1 or an extended line of the straight line L1 to a point on the boron nitride particle, and
- wherein a first portion extending in a first direction with a length of 50 μm or longer;
- and a second portion bending from the first portion and extending in a second direction different from the first direction with a length of 50 μm or longer wherein an aspect ratio of the first portion is 12.0 or less, and an aspect ratio of the second portion is 12.0 or less.
