Silicon Carbide Sintering Furnace | 2350°C Working

Pressureless Sintering for Silicon Carbide

The SJ series uses graphite resistance heating for compatible silicon carbide ceramic processing. Confirm powder chemistry, binder removal, protective atmosphere and graphite hot-zone compatibility for the intended cycle.

Applications to evaluate

• Silicon carbide components for wear, sealing and high-temperature service
• Selected recrystallized SiC or other ceramic compositions after process review

Heating rate and achieved vacuum depend on loading and process conditions. Optional chiller and lower-temperature measurement can be reviewed. Share material, part dimensions, batch load, binder and sintering cycle to request a configuration and quotation →

Planning your ceramic sintering cycle

Send the ceramic composition, binder system, part dimensions, batch load, target temperature, dwell time and required atmosphere. Size the work zone for the complete fixture and load. Review binder removal and compatibility with the graphite hot zone before selecting the furnace configuration.
