Centorr Vacuum Industries Sells Two High-Temperature Furnaces for Aluminum Nitride Production

Centorr Vacuum Industries announced it has shipped orders for two high-temperature sintering furnaces for 2015 delivery to a leading firm in the production of AlN substrates for the LED market in China.

The designs include CVI’s 2 cu ft graphite furnace for AlN sintering and a refractory metal furnace rated to 1850C for a secondary heating process. These new furnaces build on the success of CVI’s experience in non-oxide ceramics and include modifications made specifically for high-temperature sintering of advanced ceramics.

Centorr’s graphite furnace design includes robust Graphite Tube and Block elements designed for use to 2250°C, with a 4-sided hot zone and integral graphite retort for excellent temperature uniformity. The rigid graphite insulation design provides for long-term service even in the presence of process off-gassing and residual binder contamination, while the new dual-flow Sweepgas® system allows more effective “sweeping” away of the process offgassing. Furnace control is via PLC/Programmable Controllers with Centorr’s custom-designed HMI visualization interface.

Centorr Vacuum Industries Sintervac Non-Oxide design is available in sizes of 2,3,4.5,9,16,24, and 54 cubic foot volumes. The refractory metal furnace design, sized at 1 cu ft will be used for a specific part of the AlN process where a non-graphite hot zone is desired for material cleanliness. The system is rated to 1850C and offers temperature uniformity under +/- 3°C.

Centorr Vacuum Industries is a high temperature vacuum and controlled atmosphere furnace manufacturer with an installed base of over 6500 units worldwide. Their furnace offering ranges from large commercial and production units with hot zones over 3m x 3m, to smaller Lab and Research & Development furnaces for use at temperatures over 3500°C. They are located in Nashua, NH with a fully staffed Aftermarket Field Service group, and Applied Technology Center offering R&D support and toll production service.
