铝镍合成的NiAl2O4尖晶石型复合氧化物（AB2O4）作为一类重要的无机功能材料,具有熔点高、热稳定性好、硬度高、耐腐蚀、疏水性好和低表面酸性等优点,
The ni-clad-al synthetic NiAl2O4 spinel composite oxides (AB2O4),as an important kind of inorganic materials,has advantages such as high melting point,nice thermal stability,high hardness,good corrosion resistance,fine hydrophobic nature,and low surface acidity,etc.
在冶金、电子、信息、通信、家电、航空、军事、仪表、自动化、陶瓷、涂料、光学元件及催化等领域均有广泛的应用.而且还广泛应用于催化剂和催化剂载体.
It is widely applied on the fields like metallurgy,electronics,information,communications,household electrical appliances,aerospace,military,instrumentation,automation,ceramics,coating,optical components and catalyst.In addition,it is also used as the
catalyst and its carriers.
本次研究的内容主要是研究NiAl2O4尖晶石的合成及其在各种条件下进行的表征,通过溶胶凝胶技术在镍铝比例为1:2,1:4,1:8条件下以硝酸铝和硝酸镍为原料用氨水滴定合成铝镍溶胶.众所周知,氧化镍与氧化铝以相对较低的温度（400℃–450℃）,以形成一个表面镀镍,铝.
This research concerntrate on the study of contents NiAl2O4 spinel synthesis and the token under various conditions,in which the proportion of aluminum nickel under 1:2,1:4,and 1:8 conditions through sol gel technology with aluminum nitrate and nitric acid as raw material combined with nickel ammonia to use Ammonia titration to synthesis al ni sol.As is known,nickel oxide and alumina oxide can form a superficial nickel plating,aluminum at a relatively low temperature (400-450 ℃).
而在相对较高的温度下生成NiAl2O4尖晶石.由于本实验使铝含量逐渐增加,所以我们在500℃左右生成NiAl2O4尖晶石是可以被预期的,所以我们使之在500℃,700℃,900℃焙烧6个小时.
However,at a relatively high temperature NiAl2O4 spinel is generated.Since the aluminium content will be increase gradually during this experiment,it is expected that we can generate NiAl2O4 spinel around 500℃ so that we intend to roast it in 500℃,700℃,and 900℃ for 6 hours.
制取60M-40M的粉末.利用粉末进行了X-射线衍射分析（XRD）、程序升温还原（H2-TPR）表征.表征的结果表明了以上3种比例条件下在500℃只存在NiO晶体,而700℃,900℃则生成了NiAl2O4尖晶石.
Making 60M - 40 M powder and using them to conduct tokens for X-ray diffraction (XRD),program temperature restoration(H2-TPR).The results show that under the above three kinds of percentage conditions only NiO crystals exist in 500℃,and NiAl2O4 spinel is generated under 700℃ and 900℃.
