【摘要】：正钪作为稀土元素,具有独特的物理化学性质,如钪元素加到铝合金中,可以显著提高合金的再结晶温度,强烈抑制沿晶断裂倾向,提高合金强度、塑性和断裂韧性~([1-2])。近年来,随着新材料技术的迅猛发展,氧化钪(Sc_2O_3)更是广泛应用于固体氧化物燃料电池(SOFCs)~([3])、新一代激光晶体~([4])、大功率金属卤素灯、高能辐射用核能屏蔽、特种陶瓷等领域。但氧化钪中含有的杂质元素会导致这些材料性能极大下
[Abstract]:As a rare earth element, normal scandium has unique physical and chemical properties. For example, adding scandium to aluminum alloy can significantly increase the recrystallization temperature of the alloy, inhibit strongly the intergranular fracture tendency, improve the strength, plasticity and fracture toughness of the alloy ([1-2]). In recent years, with the rapid development of new material technology, SC _ 2O _ 3 (SC _ 2O _ 3) has been widely used in the field of solid oxide fuel cell (SOFCsN), new generation laser crystal ([4]), high-power metal halogen lamp, high-energy radiation nuclear energy shielding, special ceramics and so on. However, the impurity elements contained in scandium oxide lead to great properties of these materials.
