Industrial Applications of 15933-59-2
| Industry | Application | Process |
|---|---|---|
| Semiconductor Manufacturing | Silicon surface passivation | Used as a silicon surface passivating agent in chemical vapor deposition (CVD) or plasma-enhanced chemical vapor deposition (PECVD) processes |
| Electronic Materials | Production of high-purity silicon-based materials | Generates silicon nitride or silicon oxide thin films via high-temperature decomposition for use as insulating or protective layers in electronic devices |
| Catalysis | Catalyst precursor | Produces nitrogen-containing silicon-based catalysts via pyrolysis or hydrolysis for organic synthesis reactions |
| Materials Science | Synthesis of organosilicon compounds | Serves as a silicon source in organic synthesis processes, participating in hydrosilylation and siloxane bond formation reactions |
| Thin Film Deposition | Silicon nitride thin film production | Decomposes at elevated temperatures under low-pressure chemical vapor deposition (LPCVD) to form silicon nitride thin films |
| Optical Coatings | Optical coating material | Applied in vacuum evaporation or sputtering processes to produce optical coating materials with specific refractive indices |
Manufacturing Quality Control of 15933-59-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies TMDSN peak area against a calibrated standard using a non-polar capillary column and FID detection. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine generated in situ reacting stoichiometrically with water. |
| Acidity (as HCl) | Acid-Base Titration | Titrates acidic impurities with standardized sodium hydroxide solution using phenolphthalein or potentiometric endpoint detection. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates a known sample mass under controlled conditions and weighs the non-volatile residue. |
| Color | Visual Comparison or Spectrophotometry | Compares sample color to platinum-cobalt (APHA) standards or measures absorbance at specified wavelengths (e.g., 430 nm). |
| Density | Digital Density Meter | Determines density by measuring oscillation period of a U-tube filled with sample at controlled temperature. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample at 20 degrees C using a calibrated refractometer. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (Pb, Fe, Cu, etc.) | ICP-OES | Atomizes and excites sample in argon plasma; detects elemental emission lines at characteristic wavelengths. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Analyzes low-boiling impurities (e.g., hexamethyldisiloxane, ammonia) after thermal equilibration in sealed vial. |
| pH of Aqueous Solution | pH Meter | Measures hydrogen ion activity in a 1% (w/w) aqueous solution prepared under controlled conditions. |
| Non-Volatile Alkali Metals (Na, K) | ICP-OES | Quantifies alkali metals after acid digestion and dilution, using plasma excitation and element-specific emission detection. |
