Dissolution of powdered quartz
Nature, 1975POWDERED quartz exhibits an initially high solubility rate but opinions are divided as to the cause. Clelland1 argued in favour of the ‘Beilby layer’—a skin of vitreous material produced during grinding; whereas Talbot2 stated that the numerous small particles which were always found adhering to the larger particles of quartz offered a plausible ...

The Structure of Powdered Quartz
Nature, 1973DIFFERENTIAL thermal analysis (d.t.a.) of quartz normally reveals an endothermic peak at 573° C, corresponding to the inversion from low quartz to high quartz. If the quartz is subjected to grinding it is observed that the peak size decreases, both in height and area; this effect is usually attributed to conversion during grinding of quartz to some ...

Thermodynamic Properties of Methane Hydrate in Quartz Powder
The Journal of Physical Chemistry B, 2007Using the experimental method of precision adiabatic calorimetry, the thermodynamic (equilibrium) properties of methane hydrate in quartz sand with a grain size of 90-100 microm have been studied in the temperature range of 260-290 K and at pressures up to 10 MPa.

Hydrothermal synthesis of mono-dispersed quartz powders
Journal of Materials Science, 2004The hydrothermal method was first used for crystallization of quartz in the middle of 19th century, and has been developed to grow large single crystals of quartz industrially [1]. On the other hand, the hydrothermal method has been recognized as an excellent method to prepare ceramic powders [2].
