OTF-1500X-VT-III-PGEP is a multifunctional synthesis system designed for synthesizing various nanostructured oxides and composite-coating processes for nanomaterials. The instrument comprises three main modules: a gas atomizer, a 1500°C three-zone vertical tube furnace, and a collection device. The material fabrication involves approximately three steps: precursor atomization, heating, and nanoparticle collection. This system is highly advanced, allowing control over particle size, morphology, micro-nanostructure, etc., making it suitable for a wide range of applications including nano-material preparation and electrode material coating composites.

- A filter (5um mesh) is installed at the outlet of the cyclone collector, capable of collecting finer particles with a size of up to ~2um.
|
| High-pressure Atomizing and Auxiliary Gas Device |
Air compressor:
(The two-fluid atomizing nozzle requires a certain flow rate and pressure of gas to atomize the liquid)
- Power: 1350W
- Volumetric Flow Rate: 0.11m3/min
- Working Pressure: 0.7Mpa
Blower:
(To ensure that the atomized particles enter the heating furnace vertically along the furnace tube)
- Voltage: 220-240V
- Power: 0.18KW
- Max Flow Rate: 0.8m³/min
|
| Application Notes |
- The pressure inside the furnace tube must not exceed 0.02 MPa.
- A relief valve must be installed on the gas source(high pressure).
- For experiments involving sample heating, it is not recommended to close the exhaust valve and intake valve at the flange end of the furnace tube. If it is necessary to close the gas valve for sample heating, the pressure gauge reading must be monitored constantly. If the gas pressure reading exceeds 0.02 MPa, the exhaust valve must be opened immediately to prevent accidents such as furnace tube rupture or flange detachment.
- We do not recommend customers use flammable, explosive, or toxic gases. If customers need to use such gases due to process requirements, they must take their own safety precautions and explosion prevention measures. MTI is not responsible for any issues related to the use of flammable, explosive, or toxic gases.
