  1. Standard test method for determination of the proportion of phases in portland cement and portland - cement clinker using x - ray powder diffraction analysis

    用x射線粉末衍射分析測定硅酸鹽水泥和硅酸鹽水泥熔渣的階段比例的標準試驗方法
  2. 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。
  3. By using the method of burning, we fabricated the ceramic powder of al2o3, and discussed the effect of mole percentage of metal ions and urea on forming phases of al2o3. we calculated the x - ray powder diffraction by scherrer formula, and we thought that the ceramic powder reaches nano order

    採用燃燒法制備了al _ 2o _ 3陶瓷粉末，討論了金屬離子和尿素的摩爾比對al _ 2o _ 3成相的影響；對其x射線粉末衍射數據用scherrer公式計算得出所得al _ 2o _ 3陶瓷粉末已達到納米量級。
  4. The structures of their hydrides were characterized by the x - ray powder diffraction ( xrd ) method

    藉助透射電鏡（ tem ） 、 x射線粉末衍射（ xrd ）和bet法對其產物進行了表徵。
  5. 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 。
