Abstract

The invention provides a device for preparing nanometer aluminum oxide by using a nanometer porous membrane. The nanometer aluminum oxide preparation device is provided with a platform and a shell, the platform is used for supporting the whole preparation device, and an aluminum ion solution supply device, an injection device, a combustion device and a particle collection device are sequentially arranged above the platform from left to right. Compared with the prior art, the technical problem that the size of aluminum ion solution droplets jetted by the jetting device is too large is solved; the quality of the nanometer aluminum oxide particles is improved; the quality of the liquid drops obtained after the liquid drops pass through the nano-porous membrane is stabilized and refined; and nano aluminum oxide particles with different sizes can be prepared according to requirements.

Description

technical field [0001] The invention belongs to the field of material preparation, and in particular relates to a device and a method for preparing nano-alumina by using a nano-porous membrane. Background technique [0002] Nano-alumina is a commonly used material in high-tech fields. Compared with conventional materials, nano-alumina has excellent optical, electrical, magnetic, thermal and Mechanical properties, at present, nano-alumina has been widely used in aerospace, metallurgy, chemical industry, ceramics, electronics, national defense and nuclear technology and other fields. However, the current preparation of alumina is easy to introduce impurities, and the particle size of the prepared powder is difficult to reach the nanometer level; or, the disadvantages of huge equipment and expensive equipment limit its use; or, it is finally difficult to collect the required level of nano oxide aluminum. Contents of the invention [0003] In view of the above technical prob...
