Embodiment 1
[0328]
[0329] Weigh the second inorganic filler (BN) and liquid crystalline epoxy compound (compound represented by formula (6-1)) respectively 2g and 4g (the blending ratio of BN is 19% by volume) and put it on the medicine package paper, use a mortar After mixing, kneading was carried out at 120° C. for 10 minutes using a twin roll (HR-3 manufactured by Nitto Reactor Co., Ltd.). Thereafter, separation and purification were carried out by ultrasonic treatment and centrifugation to obtain liquid crystalline epoxy-decorated BN particles from which unreacted components were removed. The particles are referred to as the first inorganic filler.
[0330] The coating amount of the silane coupling agent or the liquid crystalline epoxy compound of the first inorganic filler and the second inorganic filler on the BN particles was measured using a thermogravimetry-differential thermal analysis (Thermogravimetry-Differential Thermal Analysis, TG-DTA) device (Seiko Electronics (Seiko ...
Embodiment 2
[0340] A sheet containing 47 vol % of BN and 41 vol % of AlN was produced in the same manner as sheet 2 , and was referred to as sheet 3 . Furthermore, sheet 2 and sheet 3 are laminated and cured. The obtained sheet was used as the laminated body 2 of the thermal expansion control member.
Embodiment 3
[0342] In the same manner as sheet 2, BN was 65% by volume, and Al 2 o 3 It is an 18 volume % tablet, and it is set as sheet 4. Furthermore, sheet 1 and sheet 4 are laminated and cured. The obtained sheet was used as the laminated body 3 of the thermal expansion control member.
