Manufacturing Quality Control of VANADIUM(IV) OXIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (VO2 content) | X-ray Diffraction (XRD) | Quantifies crystalline VO2 phase fraction by comparing diffraction peak intensities with reference patterns. |
| Metal Impurities (Fe, Cr, Ni, Cu, Al) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Measures elemental concentrations via characteristic atomic emission lines after acid digestion. |
| Carbon Content | Combustion-Infrared Detection | Oxidizes sample at high temperature and quantifies CO2 evolved using infrared absorption. |
| Oxygen Content | Inert Gas Fusion-Infrared Detection | Fuses sample in inert atmosphere with graphite, converts oxygen to CO, and measures via IR absorption. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular dependence of scattered laser light from dispersed particles. |
| Specific Surface Area (BET) | Gas Adsorption (N2 BET) | Calculates surface area based on monolayer nitrogen adsorption isotherm at liquid nitrogen temperature. |
| Moisture Content | Karl Fischer Titration | Quantifies water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol-based reagent. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride anions using ion-exchange column and conductivity detection. |
| Sulfate Content | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Bulk Density | Tap Density Measurement | Measures mass per unit volume after standardized mechanical tapping of a powder sample in a graduated cylinder. |
| pH of Aqueous Slurry | Potentiometric pH Measurement | Determines hydrogen ion activity in a defined suspension using calibrated glass electrode and reference electrode. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Monitors mass change versus temperature under controlled atmosphere to assess decomposition onset and weight loss steps. |
