Powder CVD Rotary Tube Furnace with Ball Milling (1000C Max.) & Gas delivery - OTF-1200X-R5-BM

0.0/5 rating (0 votes)


OTF-1200X-R5-BM  is a compact powder nitriding rotary furnace with a ball milling function.  Ammonia ( NH3) gas passes through the two-zone heating 5" processing tube which is rotatable.  YSZ ball is inside the tube and mills the powder into smaller size during rotation and nitride,which will result in the particle fully nitrided.  It may be used for preparing rare-earth-free magnetic material.
The high-temperature ball mill can be used for Mechanochemical activation of catalysts for CO2 methanation. For more applications using a ball mill, please review the article at Specifications:
