1100°C 8-Zone High Pressure Super-Alloy Tube Furnace w/ Pressure Control System - OTF-1200X-VIII-80-GF

• Please view "Isotropic round-wire multifilament cuprate superconductor for the generation of magnetic fields above 30 TMat-2014-13-4-Larbalestier-Isotropic round-wire" published by NATURE MATERIAL 3887, 9 MARCH 2014, in which an MTI High-Pressure furnace was used.

OTF-1200X-HP-VIII-80-GF is a high-pressure tube furnace with eight heating zones and a pressure control system. The processing tube is made of Ni-based superalloy (50 mm ID x 2000mm L) which can withstand high pressure (oxygen or inert gases) under 1100°C max. Its pressure control system can maintain a stable pressure during the heating process which is critical for processing Fe-based superconductive material, or new generation oxide ceramics.

Operation Instruction
Compliance & Warranty	CE certified NRTL or CSA certification is available upon request at the extra cost. One year limited warranty for lifetime support
Safety Notes	Ni-based Superalloy ( Waspaloy or equivalent) is a reliable processing tube, which has excellent ductility and tensile property so only creep deformation happens under overpressure before a cracking. Please see pics left to see Ni-based Super-alloy ( Waspaloy or equivalent) processing tube under overpressure test Attention: For the use of flammable, toxic, or corrosive gases, you must contact the MTI engineering group for the consultation to know all the prerequisites and precautionary measures.
