reducing atmospheres 中文意思是什麼
-
Reducing atmospheres, such as hydrogen or disassociated ammonia, particularly with low dew - points, may remove the protective silicon oxide protection that forms on silicon carbide
減少部分氣體的含量，比如氫或者是分離出氨，尤其是少量水蒸氣，可能會將碳化硅表面的二氧化硅保護塗層去除。 -
Perovskite - type complex oxides of la1 - xcaxcro3 compositions are attracting growing attention because of their superior electronic conductivity and excellent chemical stability in both oxidizing and reducing atmospheres, which makes them promising candidate materials for many important applications, such as interconnectors for solid oxide fuel cells ( sofc ), heating elements for high temperature furnaces, and current collecting electrodes in magneto - hydrodynamics ( mhd ). in this dissertation, the gnp ( glycine - nitrate process ) method has been employed to synthesize la1 - xcaxcro3 oxides. the synthesis and preparation, sinterability, electrical conducting properties and thermal expansion properties of la1 - xcaxcro3 oxides have been investigated
本文採用gnp （ glycine - nitrateprocess ）法制備了la _ （ 1 - x ） ca _ xcro _ 3材料，對制備方法與工藝參數、材料燒結性能、電性能以及熱膨脹性能進行了研究，分析了ca ~ （ 2 + ）含量、粉體顆粒形態對材料燒結行為、燒結緻密化溫度的影響，並研究了ca ~ （ 2 + ）含量、粉體顆粒形態對材料晶體結構、顯微結構和物理性能的影響，其目的在於為該類高溫電子導體的進一步研究利應用提供實驗和理論依據。
