Toll Furnace Capabilities

AVS offers toll furnace runs or R&D test services to our customers developing new materials or new process development using one of three on-site furnaces. AVS customers often use AVS toll furnaces to prove out a new process or product before purchasing a furnace. Other AVS customers purchase furnace toll runs to supplement small capacity overruns or to maintain some production capacity while their furnace is down for service or maintenance.

• The HIP furnace has a 6? diameter x 12? tall graphite hot zone for temperatures up to 2300°C, vacuum in the millitorr range and/or HIP pressure up to 1500 psig (100 bar). This furnace can be run with many gas types, including nitrogen below 1900°C, or with argon, helium or hydrogen at various pressures.

• The Lab furnace has a 12? diameter x 24? tall graphite hot zone for temperatures up to 1600°C, vacuum in the 10-5 torr range, and flowing or static nitrogen or argon atmospheres up to 760 torr.

• AVS has a Bell-Style (Hetherington) furnace with a 10? diameter x 20? tall molybdenum hot zone for temperatures up to 1600°C, vacuum to the low millitorr range, and flowing or static gases, nitrogen, argon, wet hydrogen or dry hydrogen atmospheres up to 760 torr.
