Abstract

A thermally conductive silicone grease composition comprising at least the following components: (A) an organopolysiloxane which is liquid at 25° C. and is represented by the following average compositional formula: RSiO, where, Ris a monovalent hydrocarbon group; and 'a' is a number ranging from 1.8 to 2.2; (B) a thermally conductive filler composed of constituents (B) to (B) given below, wherein: constituent (B) is spherical aluminum oxide powder with an average particle diameter ranging from 15 to 55 μm; constituent (B) is spherical aluminum oxide powder with an average particle diameter ranging from 2 to 10 μm; constituent (B) is aluminum oxide powder with an average particle size not exceeding 1 μm; and (C) an alkoxysilyl-containing organopolysiloxane. The composition, along with high thermal conductivity, possesses excellent handleability and low coefficient of friction.
