| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (SiB6) | X-ray Diffraction (XRD) | Quantifies crystalline SiB6 phase fraction by comparing diffraction peak intensities against reference patterns. |
| Total Boron Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Measures boron after acid digestion and plasma excitation; emission intensity correlates with concentration. |
| Total Silicon Content | ICP-OES | Measures silicon after acid digestion and plasma excitation; emission intensity correlates with concentration. |
| Oxygen Content | Inert Gas Fusion Infrared Absorption | Oxygen in sample reacts with graphite at high temperature to form CO, detected by IR absorption. |
| Nitrogen Content | Inert Gas Fusion Thermal Conductivity Detection | Nitrogen released during high-temperature fusion in helium is quantified by thermal conductivity change. |
| Carbon Content | Combustion-Infrared Absorption | Carbon oxidized to CO2 during high-temperature combustion; CO2 measured by infrared absorption. |
| Particle Size Distribution | Laser Diffraction | Measures angular scattering pattern of dispersed particles in liquid or air to calculate size distribution. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Determines mass per unit volume after standardized tapping of a known powder mass in a graduated cylinder. |
| Moisture Content | Karl Fischer Titration | Quantifies water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol-based reagent. |
| Acid-Soluble Impurities | Gravimetric Analysis | Residue after HCl/HNO3 leaching is dried and weighed to determine insoluble impurity content. |
| Heavy Metals (Pb, Cd, Cr, Hg) | ICP-MS | Multi-element detection after acid digestion using plasma ionization and mass spectrometric separation. |
| Specific Surface Area | Brunauer-Emmett-Teller (BET) Nitrogen Adsorption | Calculates surface area from nitrogen gas adsorption isotherm at liquid nitrogen temperature. |
