Abstract
(EN)
According to the present invention, when boron nitride is mixed with a resin material and a molded body is produced by using the resultant mixture, the thermal conductivity is further increased. In addition, when using a rare earth component, the usage amount thereof is reduced. The granular boron nitride can be produced by means of a method which is for producing a granular boron nitride composition and comprises a step for heat-treatinge, in a non-oxidizing gas atmosphere, a mixture composed of: (1) a boron nitride component containing boron nitride; (2) a rare earth component containing an oxide of at least one rare earth element selected from among yttrium, cerium, and ytterbium, and/or a precursor compound thereof; and (3) a calcium component containing calcium oxide and/or calcium carbonate.

Selon la présente invention, lorsque du nitrure de bore est mélangé avec un matériau de résine et qu'un corps moulé est produit en utilisant le mélange résultant, la conductivité thermique est augmentée encore plus. De plus, lors de l'utilisation d'un constituant de terres rares, sa quantité d'utilisation est réduite. Le nitrure de bore granuleux peut être produit à l'aide d'un procédé qui sert à produire une composition de nitrure de bore granuleux et comprend une étape de traitement thermique, dans une atmosphère de gaz non oxydant, d'un mélange composé de : (1) un constituant de nitrure de bore contenant du nitrure de bore; (2) un constituant de terres rares contenant un oxyde d'au moins un élément de terres rares sélectionné parmi l'yttrium, le cérium, et l'ytterbium, et/ou son composé précurseur; et (3) un constituant calcium contenant de l'oxyde de calcium et/ou du carbonate de calcium.
