Industrial Applications of DIETHOXYDICHLOROSILANE
| Industry | Application | Process |
|---|---|---|
| Semiconductors | Used as a precursor in chemical vapor deposition (CVD) for silicon dioxide film growth | Thermally decomposing dichlorodimethoxysilane at elevated temperatures to deposit high-purity silicon dioxide onto silicon substrates |
| Optical Materials | Production of high-purity optical-grade silica glass | Forming low-impurity silicon dioxide via controlled pyrolysis or plasma-enhanced processes |
| Nanotechnology | Synthesis of nano-silica particles or coatings | Employing vapor-phase reactions or sol-gel methods with dichlorodimethoxysilane as the silicon source for nanostructure fabrication |
| Electronics Industry | Dielectric layer fabrication in integrated circuits | Applying low-pressure CVD (LPCVD) or atomic layer deposition (ALD) to precisely control film thickness and uniformity |
| Polymers | Used as a coupling or crosslinking agent to enhance performance of organic-inorganic composites | Introducing siloxane bonds into polymer matrices to improve interfacial adhesion and thermal stability |
Manufacturing Quality Control of DIETHOXYDICHLOROSILANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (SiCl2O2 purity) | Gas Chromatography (GC) with FID detector | Separation and quantification based on retention time and peak area relative to calibrated standards |
| Moisture content | Karl Fischer titration | Electrochemical titration where iodine reacts stoichiometrically with water in a controlled anhydrous environment |
| Acidic impurities (HCl, H2O-derived acids) | Acid-base titration with potentiometric endpoint detection | Neutralization of acidic species using standardized NaOH solution; endpoint determined by pH inflection |
| Residual metal impurities (Fe, Cu, Ni, Cr, Al) | ICP-OES | Atomization and excitation of metals in argon plasma; quantification via element-specific emission intensities |
| Non-volatile residue | Gravimetric analysis after evaporation | Evaporation of sample under controlled conditions followed by weighing of residual solids |
| Chloride ion (free Cl-) | Ion chromatography (IC) | Separation of anions on ion-exchange column with conductivity detection |
| Volatility profile / Low-boiling impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by mass spectral identification and semi-quantitative assessment of volatile impurities |
| High-boiling impurities | Gas Chromatography (GC) with thermal conductivity detector (TCD) | Detection of late-eluting peaks indicating higher molecular weight or less volatile contaminants |
| Density | Digital density meter (oscillating U-tube principle) | Measurement of sample density via resonant frequency shift of a vibrating U-shaped tube filled with sample |
| Refractive index | Abbe refractometer | Determination of refractive index based on critical angle of total internal reflection at prism-sample interface |
| Color | Visual comparison against APHA color standard | Subjective assessment of sample color intensity relative to platinum-cobalt scale solutions |
| Particulate matter | Membrane filtration followed by microscopic examination | Filtration through defined-pore membrane and enumeration/characterization of retained particles |
