| description | The present invention provides aluminum nitride particles that have excellent high thermal conductivity, that are useful as a filler for a heat dissipating material, and that, in order to improve filling properties, have favorable fluidity. Provided are spherical AlN particles characterized by: containing Zr atoms in an amount with respect to Al atoms such that the molar ratio Zr/Al = 4.0×10-4 to 4.2×10-2; having an AlN conversion ratio of not less than 70.0%; and having a circularity of 0.85-1.00.
La présente invention concerne des particules de nitrure d'aluminium qui présentent une excellente conductivité thermique élevée, qui sont utiles en tant que charge pour un matériau de dissipation de chaleur, et qui, afin d'améliorer les propriétés de remplissage, ont une fluidité favorable. L'invention concerne des particules sphériques d'AlN caractérisées en ce que : elles contiennent des atomes de Zr en une quantité par rapport aux atomes d'Al telle que le rapport molaire Zr/Al = 4,0×10-4 à 4,2×10-2 ; elles présentent un rapport de conversion de l'AlN d'au moins 70,0 % ; et elles présentent une circularité comprise entre 0,85 et 1,00.
高熱伝導性に優れ、放熱材料用のフィラーとして有用な窒化アルミニウム粒子において、充填性を向上させるために、流動性が良い窒化アルミニウム粒子を提供する。 Ａｌ原子に対してＺｒ原子を、モル比Ｚｒ／Ａｌ＝４．０×１０-4～４．２×１０-2の量で含有し、ＡｌＮ転換率が７０．０％以上であり、円形度が０．８５～１．００であることを特徴とする球状ＡｌＮ粒子。 |
