Use of native stilbite zeolite coupled with vermicompost for improving soil chemical properties and yield of barley (Hordeum vulgare L.) grown on Aridic Calciusterts of Northern Ethiopia

open access: yesDiscover Sustainability
Nutrient deficiency and bioavailability in the low-carbon and alkaline soils of semiarid areas of Ethiopia are serious problems. Identifying novel approaches to managing soil fertility helps reverse soil degradation, thereby bolstering crop productivity ...

Structural and spectroscopic studies of alkali-metal exchanged stilbites [PDF]

open access: yesMicroporous and Mesoporous Materials, 2016
Abstract The structural, infrared (IR) and Raman spectroscopic properties of alkali-metal exchanged (Na+, K+, Rb+, Cs+) zeolites with the stilbite (STI) framework have been studied by Rietveld analysis of high-resolution synchrotron X-ray powder diffraction data, micro-Raman and synchrotron IR spectroscopy at ambient conditions.

Stilbite from bomeki, Miyagi Prefecture, Japan.

open access: yesThe Journal of the Japanese Association of Mineralogists, Petrologists and Economic Geologists, 1981
A calcium-rich stilbite occurs in the amygdaloidal cavity of the Upper Miocene dacite dyke at Bomeki, Miyagi Town, Miyagi Prefecture. Chemical analysis gave SiO2 56.38, Al2O3 15.89, CaO 7.94, Na2O 1.08, K2O.10, H2O+16.23 and H2O- 1.93wt%. Fe, Mn, Mg and P were not detected. This corresponds to Na1.00K.06Ca4.07Al8.96Si26.98O72•28.98H2O.
