Polycrystalline structure of waste slag in aluminum factory at different calcining temperature 鋁廠污泥在不同煅燒溫度的晶相結構研究
The results indicated : ( 1 ) the fe2o3 - al2o3 nanocomposites with different fe2o3 content and calcining temperature have different phases 研究表明: ( 1 ) fe _ 2o _ 3含量和熱處理溫度對復合粉末的相組成有重要影響。
Then the carbon nanotubes were purified by calcined in a suitable temperature after the acid - treatment . before the calcined process , tga was used to determine the calcined temperature 對制得的碳納米管進行了純化,純化中先對碳納米管產物進行了酸處理,然后在適宜的溫度下煅燒。
Abstract : in this paper , the preparation of the catalysts for the oxidation of fluorene to fluoreone is studied . the influences of the dipping time , calcining temperature , calcining time and the air quantity during the calcination are discussed 文摘:研究了用工業(yè)芴氣相氧化制取芴酮的催化劑制作條件,考察了浸漬時間、煅燒溫度、煅燒時間和煅燒空氣量對催化劑制作的影響
Samples with various compositions were prepared through different calcined temperature , sinter temperature and different maintained time at sinter temperature . the structure , density , shrinkage , and piezoelectric properties were investigated 選取部分組成點,采用不同的預合成溫度、燒結溫度和保溫時間制各樣品,測試各樣品的晶體結構、體積密度、線收縮率和壓電性能。
