Industrial Applications of 13450-91-4
| Industry | Application | Process |
|---|---|---|
| Materials Science | Semiconductor material preparation | Used as a gallium and iodine source for synthesizing III–V semiconductor compounds, such as in single-crystal growth via chemical vapor deposition (CVD) or molecular beam epitaxy (MBE) |
| Optoelectronics Research | Research on optoelectronic functional materials | Employed as a precursor in laboratory-scale synthesis of novel optoelectronically responsive materials, including solid-state reactions and solution-based methods |
| Chemical Synthesis | Iodide reaction intermediate | Applied as a gallium source in inorganic synthesis for metathesis or coordination reactions to prepare other gallium-based complexes or functional materials |
Manufacturing Quality Control of 13450-91-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Gallium Content | ICP-OES or ICP-MS | Quantifies Ga concentration via atomic emission (ICP-OES) or mass spectrometry (ICP-MS) after acid digestion and matrix matching. |
| Iodine Content | Potentiometric Titration with Silver Nitrate | Measures iodide ions by titration with AgNO₃ using a silver indicator electrode; endpoint corresponds to AgI precipitation completion. |
| Moisture Content | Karl Fischer Coulometric Titration | Determines trace water content electrochemically via iodine generation proportional to water in the sample. |
| Heavy Metal Impurities (e.g., Pb, Cd, Hg, As) | ICP-MS | Simultaneously quantifies ultra-trace heavy metals after microwave-assisted digestion and dilution, leveraging high sensitivity and isotope resolution. |
| Organic Volatile Impurities | Gas Chromatography–Mass Spectrometry (GC-MS) | Separates and identifies residual solvents or organic contaminants based on retention time and mass fragmentation patterns. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in dispersed solid samples by analyzing angular dependence of scattered laser light. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Determines mass per unit volume of powder after standardized tapping; reflects flowability and packing behavior. |
| pH of Aqueous Slurry | Potentiometric pH Measurement | Measures hydrogen ion activity in a defined suspension (e.g., 10% w/w in deionized water) using calibrated pH electrode. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Quantifies non-volatile inorganic impurities by measuring mass loss after high-temperature (e.g., 550 °C) ignition of dried sample. |
| Crystal Phase Purity | X-ray Powder Diffraction (XRPD) | Identifies crystalline phases and detects amorphous or polymorphic impurities by comparing diffraction pattern to reference GaI₃ standard. |
| Total Halide Impurities (Cl⁻, Br⁻) | Ion Chromatography with Conductivity Detection | Separates and quantifies halide anions based on ion-exchange retention and conductivity response after eluent suppression. |
| Sulfate Content | Barium Sulfate Gravimetric Method | Precipitates sulfate as BaSO₄ under controlled conditions and determines mass fraction by weighing the dried precipitate. |
| Appearance and Color | Visual Inspection against Standard Reference | Assesses physical state, homogeneity, and color deviation relative to established visual standards for GaI₃ (e.g., dark red-black crystalline solid). |
