METHOD FOR EVALUATING BORON NITRIDE POWDER |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide an evaluating method of evaluating the dispersibility of boron nitride powder. Ž<P>SOLUTION: The boron nitride powder having ≥0.2 μm and ≤4 μm average primary particle diameter d<SB>50</SB>and having absorption peek detected in a range of 3,600-3,750 cm<SP>-1</SP>by the measurement in diffuse reflection infrared spectrometry is selected as a non-defective product. The absorption peak is an absorption peak expressing OH group linked to boron atom by covalent bond. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
