Tridymite is a low pressure, mostly high-temperature-stable polymorph of silica that can also form or persist metastably at low temperatures. The high-temperature form occurs most notably as vapour-deposited, platey crystals in vesicles in some volcanic rocks, also rarely as phenocrysts in some felsic volcanics, or as a contact metamorphic material in some hornfels.

Substituent is limited to methyl. According to the known reaction mechanism, the reason why the geometry selection occurred is discussed by a conformational analysis of a possible intermediate, titanium bound pinacolate, and molecular orbital calculations of the starting carbonyl compounds.

2019-5-25The UV photoproduction of a hydrophilic TiO211011 surface has been investigated in a pressurized ultrahigh vacuum apparatus under controlled conditions of hydrocarbon concentration in oxygen gas at 1 atm pressure. Water droplet contact angles have been measured continuously as the droplet is exposed to UV irradiation, yielding the first observations of a sudden wetting process during.

2007-4-4This manual discusses how to prepare and X-ray samples and standards for this type of analysis and describes the operation of the program. Carefully weighed samples containing an internal standard zincite are ground in a McCrone mill. Randomly oriented preparations then are X-rayed, and the X-ray data are entered into the RockJock program.

In this study, the influences of graphite molar ratio and reaction temperature on alumina carbothermal reduction and AlN crystal growth on AlN-buffer layer were investigated to improve the AlN crystal quality. Mixed powder of alumina, graphite and zirconia was used as a source material. Zirconia suppressed the nitridation on the alumina surface.
