振蕩器用冷焊密封石英晶體振子詳細規范. dp外殼6 . 0至25mhz頻率范圍.寬溫范圍 -
Hence we combined coprecipitation method, using zinc carbonate as enclosure dose causing the crystal nucleus can not grow up, zinc titanate acts as phase - transition accelerant, thereby we can obtain rutile nanometer tio2 powder at lower calcining temperature and in briefer calcining time relatively
因此我們結合共沉澱法,引入碳酸鋅作包覆劑控製品粒長大,利用鈦酸鋅作品型促進劑,在相對較低的焙燒溫度和較短的保溫時間內制得到了金紅石型納米tio _ 2粉體。
