How to disperse nanoparticles / nanopowders (nanomaterials)?
How to disperse nano-materials and mix with other powder?
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.
How to maintain and repair SiC heated furnaces (KSL-1400X, etc)
SiC heating element's resistivity will increase when operating at high temperature, which will results in furnace power reduce; meaning temperature will not reach to more than 1300oC.
In order to keep longer service life of SiC heating element, you need rewire SiC heating element with SiC resistivity increases from
5 series and 2 parallel connection (new) (5S2P)
2 series and 5 parallel connection (middle life) (2S5P)
1 series and 10 parallel connection (old) (1S10P)
If 10P still can not give you enough power, you need to change SiC heating element and start from 5S2P connection
Please click here to see diagram on how to change wiring from 5S2P to 1S10P
Please be advised if furnace chamber cracked, you shall repair them using Al2O3 adhesive (click to order).
If crack is too larger, you shall use high temperature Al2O3 fiber to fill the cracks first, then put ceramic coating
