Description

Sinterbar™ Jr. Pressure Furnaces are vital to the efficient and economical production of a wide variety of advanced ceramics, carbide tools and wear parts, and other high performance materials. They eliminate a separate hot isostatic pressing operation for many materials with liquid phases. Overpressure capabilities permit many sinterable ceramics to be processed at higher temperature for superior properties.

The "Sinterbar" pressure furnace design allows multi‐mode operation in vacuum, partial pressures, and positive gas pressures up to 1500 psig (100 bar). Available in vertical top loading laboratory sizes with furnace temperatures range up to 1650°C for carbides and 2200°C for ceramics. For broader application in high performance engineering ceramics production, Sinterbar Jr. furnaces can be supplied with either graphite or carbon‐free hot zones for operation at tempertures to 2200°C and presures to 1500 psig (100 bar).

A complete furnace system includes all necessary controls for fully automatic operation of complete process cycles including Sweepgas™ binder removal. Sinterbar Jr. furnaces incorporate the latest developments in high temperature pressure furnace technology.

Features

Production Benefits
