Method for crystallite size determination in metal catalysts by x - ray diffractometry 用x射線衍射儀測定金屬晶體中晶粒大小的方法
X - ray diffractometry x 光繞射法
By means of x - ray diffractometry , it is found the fluorocarbon films are amorphous X - ray衍射儀對濺射沉積膜的結構進行了研究結果表明cf膜是無定型的。
Scanning electron microscopy , x - ray diffractometry , and raman spectroscopy were employed in order to determine morphology , crystal orientation , and quality 實驗中通過sem 、 xrd和raman等測試手段,對樣品的成分、結構做出分析。
Nano bn was synthesized from h3bo3 and co ( nh2 ) 2 in n2 atmosphere at 800 for 1 hour . x - ray diffractometry ( xrd ) reveals that the average grain size of bn is about 10 nm 使用硼酸和尿素作為反應原料,在800 , n _ 2氣氛中經1小時制得納米bn , x射線衍射分析( xrd )表明晶粒大小在10nm左右。
