Wettability of Fully Hydroxylated and Alkylated (001) α-Quartz Surface in Carbon Dioxide Atmosphere
Journal of Physical Chemistry C, 2019Wettability of alkylated quartz surfaces is of primary importance in several technological applications, including the development of oil and gas reservoirs and carbon geo-sequestration.

Silicon/quartz bonding and quartz deep RIE for the fabrication of quartz resonator structures
2008 3rd IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2008In this paper, silicon/quartz bonding and quartz deep RIE (DRIE) processes have been developed to fabricate micromechanical quartz resonator structures. A low temperature (< 300degC), plasma-assisted silicon/quartz bonding condition that can provide the maximum bonding shear strength of 10 MPa has been experimentally constructed.

Aluminum diffusion in synthetic and natural quartz was characterized under anhydrous conditions at 1 atm and temperatures from 700 to 950 °C. Experiments were carried out on polished quartz slabs immersed in fine-grained powder of spodumene or K-feldspar.

Proceedings of IEEE 48th Annual Symposium on Frequency Control, 2002
The outgassing of quartz crystal plates was measured with a high resolution mass spectrometer using thermal desorption techniques. As the quartz was heated from 40/spl deg/C to 1200/spl deg/C in a vacuum, the mass spectrometer identified several types of gases. The primary species that appeared were NH/sub 3/, OH, and H/sub 2/O.

QUARTZ AND PNEUMOCONIOSIS IN COALMINERS
The Lancet, 1981In a routine survey of 623 miners in one colliery, 21 men, an unusually high number, showed radiological progression of simple pneumoconiosis in spite of generally low exposures to mixed coalmine dust. Comparison of the dust exposures of the 21 men with those of matched controls without pneumoconiosis showed highly significant differences in the ...

Electron microscopy was used to investigate scratches on cleaved synthetic quartz and amethyst. The transverse bands in a scratch are microcracks. When the hardness of the indenter is less than the hardness of the quartz, a formation of Dauphine microtwins is observed near the scratch.

PYRITES (FeS2) in the form of small crystals and specks of a brassy-yellow colour may be found frequently in quartz. Four pieces of Brazilian quartz, containing pyrites inclusions, have now been found which are of unusual interest.
