Routine characterization and interpretation of complex alkali feldspar intergrowths [PDF]
, 2015 Almost all alkali feldspar crystals contain a rich inventory of exsolution, twin, and domain microtextures that form subsequent to crystal growth and provide a record of the thermal history of the crystal and often of its involvement in replacement ...

Electrorheological properties of polyaniline/K-feldspar conducting composite
Journal of Composite Materials, 2012 In this study, synthesis of conducting polyaniline (PAn)/potassium-feldspar (K-feldspar) composites, having various amounts of PAn, was carried out using (NH4)2S2O8 as oxidizing agent. The conducting composites were characterized by a series of techniques namely: Fourier transform–infrared, X-ray diffraction, scanning electron microscopy ...
