| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Chemical Composition Analysis | X-Ray Fluorescence Spectroscopy (XRF) | Rapidly determines the content of boron, nitrogen, and other impurity elements in samples; non-destructive and suitable for large-scale screening. |
| Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | High-sensitivity detection of trace metal impurities (e.g., Fe, Al, Ca); requires sample dissolution prior to testing. | |
| Elemental Analyzer (CHNS/O) | Measures nitrogen and carbon content; boron content can be derived by calculation. Suitable for verifying nitrogen content in high-purity BN powders. | |
| Phase Composition | X-Ray Diffraction (XRD) | Identifies crystal phases of boron nitride (e.g., hexagonal BN, cubic BN, wurtzite BN), assesses crystallinity, and detects presence of impurity phases. |
| Morphology | Scanning Electron Microscopy (SEM) | Observes particle morphology, size distribution, and agglomeration state; combined with Energy Dispersive Spectroscopy (EDS) for localized elemental analysis. |
| Transmission Electron Microscopy (TEM) | High-resolution observation of crystal structure, defects, and nanoscale morphology; suitable for detailed characterization of nano-BN materials. | |
| Particle Size Distribution | Laser Diffraction Analysis (LDA) | Measures particle size distribution based on light scattering principles; applicable to BN powders using dry or wet dispersion methods. |
| Dynamic Light Scattering (DLS) | Measures particle size distribution of nano-BN in suspension; suitable for quality control of nanomaterials. | |
| Specific Surface Area | Nitrogen Adsorption-Desorption Method (BET Method) | Calculates specific surface area from nitrogen adsorption isotherms; reflects material fineness and pore structure, commonly used for nano-BN or porous BN. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Measures mass changes during heating to evaluate oxidation onset temperature and thermal decomposition behavior. |
| Differential Scanning Calorimetry (DSC) | Analyzes phase transitions, crystallization, or reaction heats; used to study physical and chemical changes of BN at high temperatures. | |
| Density | Gas Pycnometry (Helium Displacement Method) | Determines true density using helium penetration; suitable for measuring density of highly dense ceramics or powder materials. |
| Purity | Comprehensive Elemental Analysis + XRD + TGA | Combines multiple methods for overall assessment: elemental analysis for impurities, XRD for phase identification, TGA for volatile content; provides estimated total purity. |
| Functional Properties (e.g., Thermal Conductivity) | Laser Flash Analysis (LFA) or Hot Wire Method | Measures thermal diffusivity; thermal conductivity is calculated using specific heat and density. Used for quality evaluation of thermally conductive filler-grade BN. |
