Effect of temperature and glass content on crystalline phases in porcelain sintered with recovered automotive glass [PDF]

open access: yesHeliyon, 2023
In the pursuit of sustainable porcelain production, this research examines the potential of using recovered automotive glass as a substitute for traditional feldspar, specifically feldspar imported from Spain. Porcelain samples were sintered at different

Ice nucleation properties of K-feldspar polymorphs and plagioclase feldspars [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
The relation between the mineralogical characteristics of size-selected feldspar particles from 50 to 800 nm and their ability to act as ice-nucleating particles (INPs) in the immersion mode is presented.

PETROGRAPHY AND MICROTEXTURAL CHARACTERISTICS OF GRANODIORITE FROM WASIMI, SOUTHWESTERN NIGERIA [PDF]

open access: yesEarth Science Malaysia, 2020
Rock samples of granodiorite from Wasimi were studied in detail to determine the minerals, mineral associations and the different micro-texture present in order to unravel the processes that were involved during the cooling of the magma.

Mid‐Infrared Spectroscopy of Feldspars From the Bühl Basalt (Northern Hesse, Germany) Formed Under Reducing Conditions as Terrestrial Analogue of Mercury for MERTIS

open access: yesEarth and Space Science, 2023
The MErcury Radiometer and Thermal Infrared Spectrometer instrument onboard the BepiColombo spacecraft is designed to investigate Mercury’s surface in the mid‐infrared (mid‐IR). Based on MESSENGER data and modeling, Mercury is thought to be evolved under

Not all feldspars are equal: a survey of ice nucleating properties across the feldspar group of minerals [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Mineral dust particles from wind-blown soils are known to act as effective ice nucleating particles in the atmosphere and are thought to play an important role in the glaciation of mixed phase clouds.

Disorder-enhanced luminescence kinetics in volcanic feldspars [PDF]

open access: yesEPJ Web of Conferences, 2020
A granitic feldspar is well-ordered and has a stable thermoluminescence signal enabling its dating with high reliability. In contrast, a volcanic feldspar (sanidine) exhibits a slight cristallographic disorder and an anomalously fast fading of the ...

The crystallization of a tin-bearing granitoid suite: The Bushveld granites in the Zaaiplaats area, South Africa [PDF]

open access: yesBulletin of the Geological Society of Finland, 1984
Alkali feldspars from the tin-bearing Bobbejaankop and Lease granites, and from the surrounding barren Main granite in the Zaaiplaats tin-field were studied by X-ray diffraction method. The temperatures and oxygen fugacities of the lowermost Main granite
