description The present invention provides boron nitride particles that can be used for preparation of a thermally conductive material having excellent thermally conductive properties and peel strength. In addition, the present invention provides a composition for forming a thermally conductive material, a thermally conductive material, a thermally conductive sheet, and a device with a thermally conductive layer, in relation to the boron nitride particles. In the boron nitride particles of the present invention, an atomic concentration ratio of oxygen atomic concentration to boron atomic concentration on a surface, detected by X-ray photoelectron spectroscopy, is 0.12 or greater, and a D value obtained by Equation (1) is 0.010 or less. Dvalue=BOH3002/BN002B(OH)3(002): Peak strength derived from a (002) plane of boron hydroxide having a triclinic space group measured by X-ray diffractionBN(002): Peak strength derived from the (002) plane of boron nitride having a hexagonal space group measured by X-ray diffraction.
