OTF-1200X-II-PEC4 1200°C Rotary Two-Zone Plasma-Enhanced Hybrid Physical-Chemical Vapor Deposition Furnace with In-Situ Evaporator, 4-Channel MFC and Vacuum Pump
The OTF-1200X-II-PEC4 is engineered for advanced laboratory-scale processing of inorganic compound powders, particularly suited for producing lithium-ion battery cathode powders with conductive surface coatings. Its design addresses the challenge of achieving uniform coating and heat treatment by combining a rotary tube furnace with plasma-enhanced hybrid physical-chemical vapor deposition (PE-HPCVD) technology.
This system integrates a tiltable rotary quartz tube furnace capable of reaching 1200°C, a 300W RF plasma generator operating at 13.56 MHz with automatic impedance matching, and an upstream evaporation boat for sublimating solid precursors. The rotary motion promotes continuous powder mixing, enhancing coating uniformity, while plasma assistance reduces the temperature required for certain deposition processes.

Hinweise zur Konfiguration und zum Betrieb
The system includes a tiltable rotary furnace frame, RF plasma generator with automatic matching network, upstream evaporation boat, four-channel MFC gas mixing station, and a dual-stage vacuum pump. Optional accessories include a computer control module for automated temperature programming and an automatic powder feeder with collection tank for continuous processing.
Users should verify the actual furnace tilt range (0–25° or 0–30°) and tube rotation speed range (0–5 or 2–10 RPM) based on the installed configuration. Flange and sealing dimensions should be confirmed for compatibility with existing vacuum and gas connections. Safety features include over-temperature protection and broken thermocouple alarms.
