For Higher-Temperature SiC ProcessingNASHUA, N.H., Dec. 10 -- Centorr/Vacuum Industries (CVI) announced it has received orders for three silicon carbide (SiC) sintering furnaces for 2005 delivery from various customers. The designs include a 2-cubic-foot and a 24-cubic-foot large-format design for SiC sintering and a vertical bottom loading design for specialty SiC processing.
CVI said these new furnaces build on its experience in nonoxide ceramics and tungsten carbide hard metals with modifications made specifically for higher-temperature SiC processing.
The design includes robust graphite tube and block elements designed for use to 2300°C, with single or multiple zones of control for excellent temperature uniformity. The insulation package has been upgraded from common felt to a rigid graphite board (with or without CFC covering) for long-term service even in the presence of process off-gassing or binder contamination. CVI's standard binder removal system (BRS) uses positive pressure flowthrough gas and includes a binder reservoir with integrated exhaust tower. For larger designs, the new dual flowthrough Sweepgas system provides inert gas to both the chamber and retort and ensures proper "sweeping" away of binders using preheated inert gas and minimum condensation of binder residue on the cold chamber walls. For complete binder destruction, instead of trapping, the larger furnace utilizes 1000°C heat for complete destruction of VOC's and the virtual elimination of offending exhaust byproducts. This proven system allows one furnace to accomplish two individual processes (binder removal and sintering), saving floor space, money, and maintenance costs for two separate pieces of capital equipment.
Furnace control is via PLC programmable controllers or Centorr's in-house custom designed HMI visualization interface using award-winning Intellution software. This event-based control offers extensive data acquisition functionality for supporting SPC and continuous improvement programs and remote system operation.
The new Sintervac SiC is available in sizes from 2,3, 4.5, 9,16,24 and 25 cubic foot volumes.
