hBN technical guide
A practical reference for evaluating hexagonal boron nitride powder in industrial formulations.
What is hexagonal boron nitride?
hBN is the hexagonal crystalline form of boron nitride. Its stacked layers explain why material properties can differ along and across the layers. This structure is relevant when assessing lubrication or heat transfer in a formulation.
How to compare particle sizes
Ask for the distribution and the measurement method. A D50 is the median on the stated basis. D10 and D90 describe the lower and upper parts of the distribution. A sieve limit, a typical range and a laser-diffraction result answer different questions. Compare values reported on the same basis.
What purity tells you
Purity describes the material composition. For applications sensitive to impurities, agree which components are measured, the reporting basis and any maximum limits. Use the specification to define acceptance criteria and the certificate of analysis to check the batch.
What to test in the finished formulation
Particle shape, dispersion, orientation and the surrounding matrix can influence performance. Define the test method and acceptance criteria for your own formulation, including the relevant operating conditions.
