SM9727 Silicon Nitride Degassing Rotor

Silicon Nitride Degassing Rotor Description

Silicon Nitride Degassing Rotor, manufactured from silicon nitride (Si3N4), is developed for degassing roles in processing equipment operating at elevated temperatures. The material's chemical inertness and thermal stability serve to mitigate volatile contamination in ceramic and semiconductor environments. Its engineered microstructure facilitates efficient gas removal while maintaining mechanical integrity under dynamic operation. This component is designed to support process optimisation by reducing impurities during high-temperature treatments.

Silicon Nitride Degassing Rotor Applications

1.       Semiconductor Manufacturing
- Used as a rotor in vacuum furnaces to achieve lower contamination by leveraging its chemical inertness. This minimises gas inclusions and benefits overall process purity.

2.       Ceramic Processing
- Applied as a degassing component in high-temperature ovens to remove trapped volatiles by leveraging its efficient gas evacuation. This enhances densification and reduces porosity in ceramic products.

3.       Industrial Equipment
- Serves as a component in degassing systems within industrial furnaces to control atmosphere composition by utilising its thermal stability. This approach reduces processing defects and improves material homogeneity.

Silicon Nitride Degassing Rotor Packing

The rotor is packaged in a cushioned, anti-static container to prevent mechanical shock and contamination. Protective wrapping and a sealed pouch safeguard against humidity and chemical exposure during transit. The packaging is designed to maintain a controlled environment, ensuring integrity prior to installation. Custom packaging options, including moisture barrier bags and foam-lined cases, are available to meet specific storage and handling requirements.
