产品描述
Product characteristics
High thermal conductivity
Excellent hydrophobicity
strong resistance to hydrolysis
Narrow particle size distribution
| Technical index | argument | |
| Particle size (μm) | D10 | ≤ 0.8 |
| D50 | ≤ 2 | |
| D90 | ≤3 | |
| Specific surface area (m²/g) | ≥1.6 | |
| Loose density (g/cm³) | ≥1.0 | |
| Solid density (g/cm³) | ≥1.7 | |
Hydrolysis test
Experimental conditions: 30g aluminum nitride, 300g pure water.
Experimental method: The degree of hydrolysis was determined by observing the experimental phenomenon and measuring the PH value of the solution.
Hydrolysis verification test at 70℃
| Time (h) | 0 | 1.0 | 2.0 | 5.0 | 10.0 | 24.0 | 48.0 | 72.0 |
| Modified AIN Powder (pH) | 5.6 | 5.7 | 5.7 | 5.8 | 5.9 | 6.1 | 6.15 | 6.15 |
| Unmodified AIN Powder (pH) | 7.6 | 9.4 | 10.2 | 10.2 | 10.1 | 9.8 | 9.6 | 9.6 |
Experimental phenomenon
Unmodified AIN is basically completely hydrolyzed after 2h at 70℃, resulting in a strong irritating ammonia taste and a large amount of caking at the bottom of the cup. The company's modified products, after 72h hydrolysis still does not have ammonia smell and no caking phenomenon, basically no hydrolysis phenomenon.
