Technical Parameter |
system structure |
- Atomization device: equipped with a 2.4MHz ultrasonic atomizer, it can atomize liquid into liquid particles and then introduce them into a tube furnace. The ultrasonic atomizer is connected to a stainless steel liquid collection tank to ensure that the liquid that has not been atomized does not enter the tube furnace.
- Heating section (tube furnace): The maximum temperature of the tube furnace can reach 1200 ℃.
- Nano powder collection: the diameter of the collection tube is 50mm, and the voltage is 30KV, which can effectively collect the nano particles brought by the flowing gas
