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 。
