The kinetics study was carried out in shock-heated gases with species measurements by high-repetition-rate time-of-flight mass spectrometry. The mass spectra indicate the formation of Si(OH)4 from the decomposition of TEOS while during HMDSO decomposition several Silicon-containing species were found, such as Si atoms, SiO and SiCH3. The ignition-delay time of the precursors in oxygen-containing bath gases was studied by observing the OH* emission signal behind the reflected shock wave. The ignition delay times of TEOS and HMDSO are strongly temperature dependent and the Arrhenius parameters were determined.\u003c\/p\u003e\u003cp\u003eSilica-particle formation and growth from TEOS and HMDSO were investigated in a hybrid microwave-plasma hot-wall reactor and a low-pressure premixed H2\/O2\/Ar flame reactor by in-situ and ex-situ measurements. Particle sizes distributions were determined by particle mass spectrometry and the spatial gas-phase temperature distribution was measured with multi-line NO-LIF thermometry.\u003c\/p\u003e\u003cp\u003eThe present research work provides data and new understanding of TEOS and HMDSO decomposition kinetics and particle formation and growth of silica nanoparticles in the gas-phase. These data can be used as input for computational fluid dynamics simulations and hence for the design of reactors for the gas-phase synthesis of highly specific nanoparticles.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783954047048\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783954047048","offer_id":40600738693213,"sku":"9783954047048","price":24.94,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/7e3fff77-4ed0-4686-a267-58edd9af8d01.jpg?v=1756879328","url":"https:\/\/shop.autorenwelt.de\/products\/gas-phase-synthesis-of-silica-nanoparticles-reaction-kinetics-synthesis-and-characterization-von-ali-abdali","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
