Hot Pressed Boron Nitride Disc, BN Disc Dia. 76 mm Packing

The disc is packaged in a foam-lined, anti-static container and sealed within a moisture barrier pouch to minimise particulate contamination and mechanical damage. It should be stored in a dry, ambient environment to prevent moisture uptake. The packaging design includes anti-vibration measures during transit, with customization options available based on specific handling and storage requirements.

Frequently Asked Questions

Q1: What operating conditions are recommended for using this BN disc?
A1: The BN disc performs optimally in ambient to moderately high temperature environments. It is advisable to operate within the specified density range and avoid rapid thermal fluctuations to maintain its structural integrity.

Q2: How is the density controlled during the hot-pressing process?
A2: Density is regulated by precise temperature and pressure control during the hot-pressing procedure. Stanford Advanced Materials (SAM) employs in-process monitoring techniques, including pressure calibration and post-process density verification, to ensure consistency within the 1.9-2.2 g/cm³ range.

Q3: What quality control measures are used to maintain the purity of the BN disc?
A3: The purity is maintained through controlled precursor material selection and quantitative phase analysis. In addition, scanning electron microscopy (SEM) is used to verify the microstructure, ensuring the product consistently meets the ≥99% specification.

Additional Information

Boron Nitride, known for its chemical inertness and thermal stability, is widely used in high-temperature applications and as an electrical insulator. Its advanced ceramic properties arise from a combination of strong covalent bonding and layered crystal structure, which allows it to withstand extreme conditions.

The hot pressing process enhances the material’s microstructural uniformity and minimises porosity. This processing technique is essential in achieving the required density and dimensional accuracy necessary for applications in demanding thermal and insulating environments.
