POUDRE D'AGREGATS A BASE DE NITRURE DE BORE
A powder essentially composed of aggregates based on boron nitride, the powder exhibiting an overall chemical composition, as percentages by weight, including between 40 and 45% of boron, between 53 and 57% of nitrogen, less than 400 ppm by weight of calcium, less than 5 %, in total, of other elements and more than 90% of boron nitride, limit included, as percentage by weight and on the basis of the combined crystalline phases, a mean circularity of greater than or equal to 0.90, a median pore size of less than or equal to 1.5 μm and an apparent porosity of less than or equal to 55%.
