Preparation in a hydrogen-oxygen flame of ultrafine metal oxide particles. Oxidative properties toward hydrocarbons in the presence of ultraviolet radiation

Structural, optical and charge transport study of rutile TiO2 nanocrystals at two calcination temperatures

“…Various methods [33][34][35][36][37] have been reported in literature to synthesize nanocrystalline TiO 2 . In this paper we have approached a simple hydrolysis method to prepare pure rutile TiO 2 nanocrystals.…”

Flame-spray pyrolysis preparation of perovskites for methane catalytic combustion

“…Many research groups developed different flame-based techniques for the synthesis of oxides and some of them are presently adopted for commercial production of SiO2 or TiO2 nanoparticles [17][18][19]. Formerly, the main limitation was due to the availability of volatile precursors to be fed to the flame.…”

Low temperature thermal properties of granular materials. [Specific heat; thermal conductivity]

“…49 and 50. Another technique used for powder manufacture is the hydrolysis and/or oxidation of the appropriate metallic [52][53][54] chloride in an oxygen-hydrogen flame.…”

“…' This technique is used on an industrial scale 53.55,56 to produce tonnage quantities of Si02' Ti02' and A1203' 52,57 and on a laboratory scale to produce 100 gram size quantities of ·Fe203' Ge02' and Zr02. 53 The oxide powders used to produce the ceramic samples we have studied were· produced by the above two techniques.…”
