Preparation and characterization of uniform spherical nanometer silver powder;
规则球形纳米银粉的制备及表征
The preparation of ZrO_2 spherical nanometer powders via emulsion processing route;
用乳液法制备ZrO_2纳米球形颗粒
The results show that SiO2 is amorphous sphere at a 40nm diameter, and its surface has a lot of hydroxyl groups, which can form an absorption film on metal surface
The experimental results of XRD and SEM show that the CaS:Mn2+, Eu2+ phosphors possess the crystalline structures with sphere, the mean grain sizes of phosphors are 250-400nm.
High purity spherical-normal spherical submicron crystal silica is prepared by using technique of mixing acid corrosion(anhydrofluoric acid and sulphuric acid) and method of mechanical stir from raw powder quartz.
