Synthesis and indexes of x - ray powder diffraction data of the complex of thioglycolic acid and trivalent antimonyion
瑞香素稀土配合物的合成和性質 -
We continued to use the rietveld method of whole pattern fitting of the x - ray powder diffraction data, then found that additive mgo may bring the crystal thinning of al2o3 ceramics, which can improve many properties of ceramic materials. meanwhile, we discussed the operation mechanism of the crystal thinning
然後對其x射線粉末衍射數據進行rietveld全譜擬合，得知mgo的添加可以細化al _ 2o _ 3陶瓷的晶粒，晶粒的細化可以提高陶瓷材料的許多性能，同時對其細化晶粒的作用機理進行了討論。 -
The alloy structure has been shown by x - ray powder diffraction. x - ray photoelectron spectroscopic data have confirmed that the nickel and cobalt in the bimetallic nanoclusters is in the zero - valence state and alloy state, respectively
利用差熱分析、紅外光譜、 x射線粉末衍射和透射電子顯微鏡對反應的氧化過程、結晶過程和產物的結構與形貌進行了表徵。 -
The sample composition was analyzed by means of tg and x - ray diffraction. the following conclusions can be drawn from the experiments : given conditions, the sample powder that has the same xrd data as the standard fetioa can be gotten when use any method mentioned above ; the key in synthesis is to avoid the oxidation of fe2 +, so the whole process should performed under vacuum or neutral atmosphere, samples used by this study were prepared under nitrogen atmosphere ; the heat - treated time and temperature have some influence on the sample powder, results show that the proper time and temperature is 120 minutes and 1100 respectively
研究結果表明：在合適的反應條件下，用上述三種合成方法都能得到xrd數據與標準fetio _ 3物相基本吻合的粉體；合成反應需要克服的主要問題是防止體系中fe ~ （ 2 + ）的氧化，因此，整個反應必須在真空或者非氧化性氣體保護下進行，本研究需要的樣品是在高純從保護下合成的；煅燒的時間和溫度對最終的產物也有一定的影響，研究發現：合理的煅燒時間和溫度分別為120分鐘和1100 。
