SM9736 Silicon Nitride Furnace Liner

Silicon Nitride Furnace Liner Description

Silicon Nitride Furnace Liner is manufactured from Si3N4 in a plate form, engineered for use in high-temperature furnace environments. The material exhibits outstanding thermal stability and chemical inertness, which supports operational efficiency by minimising oxidation and thermal shock. Its controlled microstructure enhances durability during prolonged exposure to elevated temperatures, ensuring predictable performance in both batch and continuous industrial processes.

Silicon Nitride Furnace Liner Applications

1.       Industrial Furnaces
   - Used as an internal lining in industrial furnaces to reduce heat loss by leveraging high thermal resistance. This application improves energy retention while protecting furnace walls.
   - Applied as a barrier in combustion systems to minimise chemical degradation by exploiting the material’s inert properties.

2.       Semiconductor Processing Equipment
   - Utilised as a liner in processing chambers to achieve controlled high-temperature environments by taking advantage of low contamination characteristics.
   - Employed in annealing furnaces to maintain stable thermal conditions, which supports precise temperature control during semiconductor production.

Silicon Nitride Furnace Liner Packing

The liner is packaged in specialised, vibration-damping containers with anti-static foam inserts to protect against impacts and particulate contamination. Storage guidelines recommend a dry, temperature-controlled environment and minimal exposure to corrosive agents. Custom packaging options, including sealed crates and detailed labelling, are available to meet specific transportation and onsite handling requirements.

Frequently Asked Questions

Q1: What is the maximum operating temperature of the furnace liner?
A1: The liner is engineered to withstand high temperatures typically encountered in industrial applications. Testing indicates that it remains stable and maintains its structural integrity well above 1,200°C. However, actual performance may depend on the specific operational conditions.

Q2: How does Si3N4 contribute to performance in furnace applications?
A2: Si3N4 offers excellent thermal shock resistance and chemical inertness. These properties help maintain a consistent thermal profile and reduce oxidation risks, ensuring the liner provides a durable protective barrier during prolonged high-temperature exposure.

Q3: Are customisation options available for dimensions and form factor?
A3: Yes, Stanford Advanced Materials (SAM) can customise dimensions, thickness, and plate geometry to align with specific furnace configurations and process requirements. Customers are encouraged to specify detailed requirements to ensure compatibility with their industrial setups.
