中文拼音 [níhuàwù]
鈮化物
英文
niobide-
So the study and use of compound powders and thin films get more and more regards. among them the double layered structure nanocompound semiconductor become the focus of study by their high photocatalytic efficiency, fast reaction speed etc. it has been confirmed that the potassium niobate ( k4nb6o17 ) is an excellent semiconductor photocatalyst. its special construction consists in the ion k + in the interlayer can be replaced by other cations, which providing vast space of modifying the material
層狀化合物中的鈮酸鉀k _ 4nb _ 6o _ （ 17 ）已被證實是一種性能優異的半導體材料，具有光催化和光電轉換性能，其獨特的結構是處于層間的帶正電的k ~ +可以被其它陽離子所替代，正是由於其多元素、復合型的特點，為材料的修飾和改性提供了廣闊的技術空間。The boundary of ferrite has been clarified and fined by adding re into crsomo. the intergranular corrosion induced by solution chromium decreasing can be restrained for nb, v, ti combing carbon in the steel. the wear resistance of stainless steel can be increased for the precipitation of microalloyed carbides
其中，稀土能夠凈化鐵索體晶界，並起到變質劑的作用，細化鐵素體晶粒，改善不銹鋼的韌性；鈮、釩、鈦能夠與鋼中的碳結合，減少固溶鉻的損失，從而避免晶間腐蝕，同時細小微合金碳化物的沉澱析出可提高不銹鋼的耐磨性。There are distinct changes about shifts or intensity in bulk plasmon, surface plasmon, and interband electron transitions losses as a result of oxidation of specimens, and adsorption and oxidation processes can be studied through these changes. at room temperature, the formation of oxide layers on uranium and uranium - niobium alloys were found to occur rapidly upon exposure to oxygen, and the resultant oxide in each case was near - stoichiometric uo2. due to formation of niobium oxide in uranium - niobium alloys, the diffusion of o ~ ( - ) ( o ~ ( 2 - ) ) and u ~ ( 4 + ) in the interface region was prevented, and the corrosion resistance of uranium - niobium alloys to oxygen is greatly enhanced by alloying with niobium
研究結果表明：清潔表面鈮和鈾的體等離子體振蕩所造成的電子能量損失的實驗值與理論計算值較為符合；隨著氧化程度的加劇，表面等離子體（ sp ） 、體等離子體（ bp ）以及價帶電子躍遷所造成電子能量損失的譜峰發生了明顯的連續偏移或強度的變化，這些變化可以用來分析鈾及鈾鈮合金的初始氧化過程；室溫下，鈾及鈾鈮合金很容易與氧作用，最終結果，鈾僅氧化為二氧化鈾，另外，在鈾鈮合金氧化過程中，因為有鈮的氧化物存在，不利於氧和鈾在界面擴散，增強了鈾鈮合金抗氧化性能； eels能獲得樣品表面的信息比aes更為表面，更為靈敏，但由於eels的譜線過于集中，主要在幾十ev以內，也有不容易區別和解譜的不足。Sales of these magnets, crafted from niobium - based compounds and alloys, continue to grow
這些以鈮化合物及合金製作成的磁鐵，銷售量持續成長。分享友人
