In this paper, co3o4 nano - particles were prepared by homogeneous precipitation method, technical conditions and kinetics were studied, the main contents and results are as follows : co ( no3 ) 2 6h2o was used as raw materials, and co ( nh2 ) 2 was used as precipitator, co3o4 nano - particles were prepared by homogeneous precipitation. the influences of concentration, molar ratio of reactants, reaction temperature and time, dryness temperature and time, and calcining temperature and time on particle size were investigated
本文採用均勻沉澱法制備納米co _ 3o _ 4粉體材料，研究了制備工藝條件、沉澱反應和前驅體熱分解過程的動力學，主要研究內容及結果如下：以硝酸鈷為原料，尿素為沉澱劑，採用均勻沉澱法制備納米co _ 3o _ 4 ，考察了硝酸鈷濃度、反應物摩爾比、反應溫度和時間、乾燥溫度和時間、煅燒溫度和時間等條件對產物粒徑的影響。It was showed that the primary coarse silicon particles could be solidified during rapid solidification and the thermoelectric properties would be worsened if the si : fe mole ratio were larger than 2. 3
研究發現，當si過量較多（ si : fe摩爾比超過2 . 3 ）時，析出了粗大的初生si顆粒，從而降低材料的熱電性能。It was found that both number and sizes of the silicon particles are increased and the ratios of electric to thermal conductivity were decreased with the increase of the silicon content. the maximal seebeck coefficients occur when the si : fe mole ratio are between 2. 0 and 2. 1
發現隨著si含量的增加，彌散分佈的si顆粒增多，顆粒尺寸增大， 「電導率/熱導率」比值降低，但seebeck系數呈現先增加后減少的趨勢，在si : fe摩爾比為2 . 0 2 . 1時達到最大值。In cvd support method, carbon nanotubes were prepared with the supported fe catalyst on the regular mesoporous molecular sieve mcm - 41 by catalytic pyrolysis of c2h2. the author studied systematically the effect of different react conditions on the structure, property and thermal - stability of mcm - 41, and reached an optimum condition of prepared mcm - 41, whose mesoporous diameter was about 2. 9nm, with 0. 12 c16tmabr : 1teos : 0. 24naoh : 66. 7h2o under hydro - thermal condition
Cvd基體法制備碳納米管中，首先探索了不同反應條件對mcm - 41材料結構性能和熱穩定性的影響，優化工藝參數，結果發現水熱條件下反應物的摩爾配比為0 . 12c16tmabr ： 1teos ： 0 . 24naoh : 66 . 7h2o時制得的mcm - 41材料最適合用來作為催化劑基體材料，其孔徑大小為2 . 9nm左右。分享友人
