Frequently Asked Questions
Answers to common questions about selecting and using industrial ceramic materials.
If your application has specific technical requirements, please contact us for evaluation.
Yes. We support:
- Custom non-standard dimensions
- Small-batch prototyping
- Trial production for R&D projects
For bulk orders, we can provide more cost-effective production solutions.
· Avoid mechanical impact and excessive stress.
· For cleaning, use alcohol or appropriate solvents depending on the working environment.
· Avoid strong acid/alkali unless the material is verified to be chemically compatible.
· Store in a dry, dust-free environment.
Please provide the following key information:
· Operating temperature range
· Working atmosphere (vacuum, inert gas, air, etc.)
· Mechanical load and structural requirements
· Required electrical or thermal properties
Based on these factors, we will recommend suitable materials such as BN, PBN, AlN, Alumina, etc.
Wall thickness selection depends on:
· Structural rigidity requirements
· Thermal stress during heating/cooling
· Installation and mechanical fixation method
Thin walls improve heat transfer efficiency but reduce mechanical strength.
Thicker walls increase durability but may affect thermal response.
We recommend optimizing thickness based on actual working conditions.
PBN (Pyrolytic Boron Nitride):
- Manufactured by CVD process
- Ultra-high purity (>99.9%)
- Excellent performance in vacuum and high-temperature environments
- Commonly used in MBE, OLED evaporation, and semiconductor processes
Hot-pressed BN:
- More cost-effective
- Good machinability
- Suitable for general high-temperature insulation and structural applications
Choose PBN for ultra-high purity and vacuum-critical processes.
Choose BN for cost-effective engineering applications.
BN (Boron Nitride)
- Excellent thermal shock resistance
- Good electrical insulation
- Easy to machine
- Suitable for high-temperature vacuum applications
Alumina (Al₂O₃)
- High mechanical strength
- Cost-effective
- Good wear resistance
Aluminum Nitride (AlN)
- High thermal conductivity
- Excellent electrical insulation
- Suitable for electronic and thermal management applications
Material selection depends on thermal, electrical, and mechanical requirements.
Hot-pressed BN can typically operate:
- Up to ~2000°C in inert atmosphere
- Lower temperature in air due to oxidation
Actual maximum temperature depends on atmosphere and mechanical load.
Heating:
- Avoid rapid temperature increase
- Ensure uniform heating
- Recommended gradual ramp-up depending on part size
Cooling:
- Avoid sudden quenching
- Gradual cooling reduces thermal stress
- Large components require slower cooling rates
Improper thermal cycling may cause cracking.
Yes.
BN / PBN materials are widely used in:
- Plasma systems
- Vacuum evaporation processes
- Semiconductor manufacturing
- High-temperature furnace components
However, material grade and structural design must match actual working conditions.
