Amorphous Coatings on Mineral Surfaces
1973
Jones, R. C. | Uehara, G.
Amorphous coatings on mineral surfaces too thin to be resolved by most electron microscopes were detected bridging particles suspended over holes in the supporting substrates. The coatings are gel-like in appearance, may flow when wet, shrink and become porous when heated, cement primary particles into large masses, and exhibit a coat-of-paint effect with curved solid-air interfaces. Amorphous gel coatings were found in alumino-silicate systems, in high aluminum soils, and on quartz surfaces.
