Abstract: The present disclosure provides a preparation method of nano-aluminum oxide (nano-Al2O3) with a controllable hydroxyl content, belonging to the technical field of nano-alumina. H2O2 dissolved in water dissociates a large number of hydroxyl radicals. In the present disclosure, a resulting H2O2 solution is used as a solvent for precipitation; during the precipitation, a soluble aluminum salt and a pore-enlarging agent are reacted to generate a precipitate under alkaline conditions, and the hydroxyl radicals are distributed on a surface of the precipitate. During drying, the hydroxyl radicals are converted into bound water and distributed on a surface and in pores of an aluminum hydroxide precursor; during roasting, the bound water is destroyed to form hydroxyl. The hydroxyl content of the nano-Al2O3 can be regulated by controlling a concentration of the H2O2 solution, and the nano-Al2O3 has the hydroxyl content positively correlated with the concentration of the H2O2 solution.

Abstract: The invention discloses a method about the integration of the metallurgical purification of metallic gadolinium and the preparation of gadolinium oxide nanoparticles (GONPs) by arc plasma. The method includes the metallurgical purification and the nanoparticle preparation. Firstly, the gadolinium ingot and a tungsten rod respectively act as an anode and a cathode. After the arc furnace is evacuated and then is filled with a working atmosphere, impurities in the gadolinium ingot are removed in the form of volatilization to obtain purified gadolinium by the first arc discharge. Whereafter, the purified gadolinium and the tungsten rod are used as the anode and cathode. After the arc furnace also is evacuated and then also is filled with a working atmosphere, GONPs are obtained from the inner wall of the arc furnace though the second arc discharge. The metallurgical purification of metallic gadolinium and the preparation of GONPs were integrated by arc plasma.
