SM9713 Silicon Nitride Exhaust Hood

Silicon Nitride Exhaust Hood Description

The Silicon Nitride Exhaust Hood is constructed from high-purity Si₃N₄, a ceramic known for low thermal conductivity and resistance to oxidation. The material’s properties enable efficient management of heat and corrosive byproducts in industrial exhaust environments. Its engineered hood shape facilitates integration into existing ductwork systems while minimising deposition of particulate contaminants. This configuration supports stable operational conditions in processes that involve high thermal cycling and chemical exposure.

Silicon Nitride Exhaust Hood Applications

Industrial Processing
• Used as an exhaust hood in high-temperature furnace systems to achieve reduced chemical deposition by employing Si₃N₄’s heat resistance. This minimises downtime due to maintenance.

Semiconductor Manufacturing
• Applied as a containment component in microelectronic fabrication systems to achieve controlled thermal flow by exploiting chemical inertness. This ensures stable environment control for sensitive processes.

Silicon Nitride Exhaust Hood Packing

The Silicon Nitride Exhaust Hood is packaged in anti-static foam and sealed moisture barrier bags to protect against physical shocks and environmental contamination. The packaging is designed to prevent dust ingress and chemical exposure during transit. Store the product in a dry, temperature-controlled environment to preserve its structural and chemical properties. Custom packaging options, including cushioned inserts and secure trays, are available for specific handling requirements.
