Manufacturing Quality Control of Aluminum nitride
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Nitrogen Content | Inert Gas Fusion - Thermal Conductivity (or Infrared Absorption) | The sample is melted in a high-temperature inert atmosphere, releasing nitrogen gas, which is then measured by a thermal conductivity detector or infrared analyzer. This method offers high accuracy and is suitable for ceramic powders. |
| Oxygen Content | Inert Gas Fusion - Infrared Absorption | The sample is melted in a graphite crucible under high temperature in an inert atmosphere, releasing CO and CO₂, which are detected by an infrared detector to determine oxygen content. Commonly used for analysis of high-purity ceramic materials. |
| Purity (Total Impurity Content) | X-Ray Fluorescence (XRF) or ICP-OES/MS | XRF is used for rapid determination of major components and primary impurities; ICP-OES/MS offers higher sensitivity and can detect trace metal impurities at ppm levels. |
| Phase Composition | X-Ray Diffraction (XRD) | Analyzes crystal structure via diffraction patterns to identify the presence of the main AlN phase and any impurity phases (e.g., Al₂O₃, AlON), used for assessing phase purity. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Measures particle size distribution based on laser light scattering, reflecting powder uniformity and processability. Applicable to both dry and wet dispersion methods. |
| Specific Surface Area | BET Surface Area Method (Gas Adsorption) | Determines specific surface area using nitrogen adsorption-desorption isotherms and the BET equation, indicating particle fineness and reactivity. |
| Microstructure (Morphology) | Scanning Electron Microscopy (SEM) | Observes particle morphology, agglomeration state, grain size, and distribution. Can be combined with EDS for micro-area compositional analysis. |
| Density (True Density) | Helium Pycnometry | Determines true density by measuring the volume displaced by helium gas in a sealed chamber, suitable for porous or ceramic materials. |
| Thermal Conductivity | Laser Flash Analysis (LFA) or Hot Wire Method | LFA calculates thermal diffusivity by measuring the rate of temperature rise on the rear surface of a sample, then derives thermal conductivity using specific heat and density. A key performance indicator for AlN ceramics. |
| Dielectric Properties | Impedance Analyzer (LCR Meter) | Measures dielectric constant (εᵣ) and dielectric loss tangent (tanδ) at specific frequencies to evaluate insulation performance in electronic packaging applications. |
