Microwave Energy for Expanding Perlite Ore

Journal of Applied Research and Technology, 2013
Perlite is an igneous mineral composed by silicon, aluminum, oxygen and water. It can be expanded by heating it upat temperatures above 870 °C, then it becomes plastic, and the steam formed inside pressures out of the mineral.Maximum expansion is possible if the particles are heated up quickly, since the expansion degree strongly dependson the ...

Collapse potential and ultrasonic pulse velocity of loess soils after treatment with expanded perlite and metakaolin

Acta Polytechnica CTU Proceedings, 2023
Collapsible soils, including loess, can support heavy loads at their natural humidity but then collapse rapidly and lose a substantial volume when the humidity increases. Soil collapse potential at different immersion stresses was investigated according

Nutritional properties, traditional uses and potential new applications for the sotol plant (Asparagaceae, Convallarioideae): A review

PLANTS, PEOPLE, PLANET, EarlyView.
Sotol (Dasylirion spp.) is a resilient desert plant that sustains ecosystems, cultures and livelihoods in Chihuahua Desert. Our review highlights its nutritional properties, traditional uses and potential new applications in food, pharmaceuticals, renewable energy and water remediation. By synthesizing evidence across disciplines, we show how sotol can

Influence of Tramp Elements on Phase Transformations, Structure, and Properties of Scrap‐Based Steels: A Focused Review of Recent Developments

steel research international, EarlyView.
This review explains how impurities from recycled scrap affect steel production and performance. Even small amounts (far below 1%) of these impurities can change how steel behaves during fabrication but also affect the properties of the end product. With better understanding and targeted countermeasures, these challenges can be managed, enabling wider ...
