After the vacuum dry and the sphere mill, the level of agglomeration is low, the particle size is very small, spherical and the nanometer stannic dioxide powder with the aspects of good scattered nature is achieved
經真空乾燥和球磨粉碎后得到團聚程度低,粒度細小均勻,達到納米水平並具有較好分散性的球形二氧化錫粉體。This edta route has several remarkable advantages in comparison with other method. because of the greater ability of edta anions to chelate metal cations, and forming very stable and soluble complexes, all of the starting materials are mixed at the molecular or atoms level in a solution, it is easy to control the composition and a high degree of homogeneity is achievable
傳統的合成方法是高溫固相反應,由於灼燒溫度高、灼燒時間長,形成硬團聚體,產物粒徑較大,一般為m級,需進行球磨粉碎以減少其粒徑,很難制得均相、均一粒度分佈的氧化物粉體,在研磨過程中容易引入雜質且晶形破壞使得發光亮度減小。The samples were characterized contrastively by sem, tem, saed, positron annihilate and the different mechanism for two methods were preliminarily discussed. the experimental results showed that nano - cuo prepared by sol - gel method was spherical, which was agglomerated badly and can aging easily. however, nano - cuo prepared by pressure - hydrothermal method has loose and thin - piece appearance structure
結果表明,溶膠-凝膠法制得的氧化銅粉末呈類球形,團聚嚴重,易老化;而壓力-熱液法制得的氧化銅具有疏鬆的、薄片狀的外觀結構,粒子厚度約為20nm ,分散性較好、抗老化能力強;壓力-熱液法制備的氧化銅比溶膠-凝膠法制備的氧化銅缺陷濃度小。The change of hot strength of iron ore pellets during oxidizing roasting and reduction was researched
摘要研究了球團礦在氧化焙燒和還原過程中抗壓強度的變化規律。A critical temperature was found, at which the strength of pellets is severely dropped during the oxidizing roasting
使用可調氣氛高溫抗壓試驗機研究了相應球團礦在氧化焙燒過程中的強度變化規律。分享友人
