Microstructure development in lithium lanthanum titanate solid electrolyte
All-solid-state batteries are one of the key technologies for future energy storage and the transition to a climate-neutral society. They offer improved safety, stability, and a broader operating temperature range compared to conventional batteries with liquid electrolyte. Perovskite Li0.33La0.56 0.11TiO3 (LLTO) is recognized as one of the most promising solid …
Influence of temperature on the hydration of belite-calcium sulfoaluminate cements
In this doctoral thesis influence of different temperatures (5 °C - 60 °C) on the hydration of belite-ye’elimite-ferrite cement was studied. Fluctuations in temperature can cause changes in the phase assemblage, kinetics of hydration and mechanical properties. Besides temperature, other factors such as the cement clinker phase composition, calcium sulfate …
Charge compensation mechanisms and twinning in doped SnO2-based ceramics
Tin (IV) oxide, SnO2 (cassiterite), is an n-type semiconductor with an advantageous combination of chemical, electric and optical properties that make it suitable for a range of applications, from solid-state gas sensors, transparent conductive coatings, oxidation catalysts and varistors. In varistor ceramics, grain growth studies are of particular interest, because …
