Abstract
A thermal-conductive silicone composition containing: (A) a hydrolysable organopolysiloxane having an alkoxysilyl group; and (B) aluminum nitride particles having an average particle size of 0.5 μm or more and 2.0 μm or less and contained in an amount of 50 to 70 volume %. A content of coarse particles in the aluminum nitride particles is 1.0 volume % or less relative to the entire aluminum nitride particles, the coarse particles having particle sizes of 10 μm or more according to a particle size distribution measurement method by laser diffraction. The thermal-conductive silicone composition has a heat conductivity of 1.3 W/mK or more according to a hot disc method. The present invention provides: a thermal-conductive silicone composition having high heat conductivity and being compressible to 10 μm or less; and a production method of the thermal-conductive silicone composition.
