1. Okt. 2022 · Environmental remediation and sustainable energy generation via photocatalytic technology using rare earth metals modified g-C3N4: A review
This chapter discusses the 2nd rare earth permanent magnetic alloy, the 2:17 type rare earth cobalt permanent magnetic alloy (RE2Co17).
29. Apr. 2009 · Rare-earth doped ZnO nanoparticles are found to be suitable for white light generation [16]. Here, we report the synthesis of pure and rare-earth doped Ga 2 O 3 nanoparicles by a simple solvothermal route. It is found that Ga 2 O 3 nanoparticles sensitize the rare-earth activator, and produce bright green, red and white light.
Rare-earth elements occur in nature in combination with phosphate ( monazite ), carbonate - fluoride ( bastnäsite ), and oxygen anions. In their oxides, most rare-earth elements only have a valence of 3 and form sesquioxides (cerium forms CeO2 ). Five different crystal structures are known, depending on the element and the temperature.
1. Okt. 2023 · Rare earth pyrosilicates such as β-Yb 2 Si 2 O 7 are identified as promising candidate materials for EBC applications due to their thermal stability at high temperatures, high resistance to oxidation and corrosion, and possible good match of CTE with the Si-based CMCs [5].
