実験手順

First, 60 kg of orthoboric acid, manufactured by NIPPON DENKO CO., LTD. (hereinafter, this product was used as orthoboric acid), 50 kg of melamine, manufactured by DSM, Ltd. (hereinafter, this product was used as melamine), and 1 kg of calcium carbonate as a Ca compound, manufactured by SHIRAISHI KOGYO, Ltd. (hereinafter, this product was used as calcium carbonate), were mixed by a Henschel mixer. Next, the mixture was placed in a constant temperature and humidity chamber at a temperature of 90° C. and a relative humidity of 85% for 5 hours to produce melamine borate. Then, the melamine borate was subjected to calcination and crystallization in a batch atmosphere furnace under a nitrogen atmosphere at 2000° C. for 2 hours to yield boron nitride with a graphitization index (GI) of 0.86 and a specific gravity of 2.27 g/cm3. After that, grinding was adjusted to prepare D-1 with a volume-average particle diameter of 18.0 μm.
