A study of factors affecting on the zeta potential of kaolinite and quartz powder
Environmental Earth Sciences, 2010 The purpose of this study was to determine the effects of pH, ion type (salt and metal cations), ionic strength, cation valence, hydrated ionic radius, and solid concentration on the zeta potential of kaolinite and quartz powder in the presence of NaCl, KCl, CaCl2, CuCl2, BaCl2, and AlCl3 solutions.

Solvothermal Synthesis of α-Quartz Powder Doped with Germanium
Zeitschrift für Naturforschung B, 2008 Experimental investigations concerning the synthesis of Si1−xGexO2 solid solutions with quartz structure have been carried out under solvothermal conditions from sol-gel preparations. The cell parameters of the powders have been determined by X-ray powder diffraction. The amount of germanium inside the SiO2 structure was measured also by electron probe

The Application of X-ray Powder Diffraction to Marble Definition and Classification
Yankuang ceshi, 2014 Marble primarily consists of three types: calcite, dolomite and magnesite. Marble classification is based mainly on the structures and mineral compositions seen under the microscope. It is very difficult to determine calcite, dolomite and magnesite under
