Disperse nanoparticles: 1. If used in the aqueous phase, may use ultrasonic treatment to disperse; 2. If used in oil phase, may use high shear mixing instrument to disperse. 3. If directly used as dry powder form, may use ball mill treatment to disperse. .
How to disperse nano-materials and mix with other powder? There is no specific method of the world. It is still a research topic. In general, if one nanomaterial will be mixed with other powder (for example: your ceramic powder), the first step is to put the nanomaterial into water or ethanol in the high-speed mixing instrument, add 1% dodecyl benzene sulfonate (detergent main ingredients), Instantly after mixing, then put the dispersed nanomaterial into the other powder (your ceramic powder) and continue to mix by still using high-speed mixing instrument, stirring rate the higher the better, time the longer the better as well, and then heating the mixed liquid material to be evaporated completely.

3. The Methods of Nanoparticle Dispersions:
Rule: The smaller the particle size, the greater the surface area, the better the particle activity. That is, the nanoparticles can fully reveal the nano-properties..
Safety: Nanoparticles present possible dangers, both medically and environmentally. Most of these are due to the high surface to volume ratio, which can make the particles very reactive or catalytic. They are also able to pass through cell membranes in organisms, and their interactions with biological systems are relatively unknown.
