Abstract:
(EN) Provided is a coated magnesium oxide particle that exhibits a high fillability and a high mass productivity, and is advantageous as a thermally conductive filler. The coated magnesium oxide particle is a coated magnesium oxide particle in which the surface of a magnesium oxide particle is coated with at least one of a fatty acid and a fatty acid metal salt. Expressing the X of a particle as X = [BET specific surface area diameter derived from the BET specific surface area of the particle]/[D50 of the particle] (where D50 is the particle diameter at a cumulative 50% in the cumulative particle size distribution of the particle), the magnesium oxide particle has an X of less than 0.2 and a D50 of 5 to 100 μm and the coated magnesium oxide particle has an X of at least 0.2, a D50 of 5 to 100 μm, and an oil absorption of less than 25 mL/100 g.
(FR) L'invention concerne une particule d'oxyde de magnésium revêtue qui présente une capacité de filtration élevée et une productivité en masse élevée, et qui est avantageuse en tant que charge thermoconductrice. La particule d'oxyde de magnésium revêtue est une particule d'oxyde de magnésium revêtue, la surface de la particule d'oxyde de magnésium étant revêtue d'un acide gras et/ou d'un sel métallique d'acide gras. Si l'on exprime le X d'une particule tel que X = [diamètre de surface spécifique BET dérivé de la surface spécifique BET de la particule]/[D50 de la particule] (où D50 est le diamètre de particule à 50 % cumulés dans la distribution de taille de particule cumulée de la particule), la particule d'oxyde de magnésium a un X inférieur à 0,2 et un D50 compris entre 5 et 100 µm et la particule d'oxyde de magnésium revêtue a un X d'au moins 0,2, un D50 compris entre 5 et 100 µm, et une absorption d'huile inférieure à 25 ml/100 g.
(JA) 充填性及び大量生産性が高く、熱伝導性フィラーに好適な被覆酸化マグネシウム粒子を提供すること。被覆酸化マグネシウム粒子は、酸化マグネシウム粒子の表面が脂肪酸及び脂肪酸金属塩の少なくとも一方で被覆された被覆酸化マグネシウム粒子であって、粒子のXを、X=[前記粒子のBET比表面積から算出されるBET比表面積径]÷[前記粒子のD50](但し、D50は前記粒子の累積粒度分布の累積50%における粒子径)としたとき、酸化マグネシウム粒子はXが0.2未満、D50が5~100μmであり、被覆酸化マグネシウム粒子はXが0.2以上、D50が5~100μm及び吸油量が25mL/100g未満である。
