BN5027 Spherical Boron Nitride Powder

Spherical Boron Nitride Powder Description

Spherical boron nitride powder possesses an isotropic thermal conductivity due to its unique particle structure, overcoming the disadvantages of the anisotropic thermal conductivity of flake boron nitride. It achieves good planar thermal conductivity at a lower filler loading. It also shares advantages such as low density and a low dielectric constant, similar to regular boron nitride. At the same filler loading, the thermal conductivity of spherical boron nitride is more than three times that of standard platelet boron nitride powder.

The density of products in the SSBNL series is lower than that of SSBN, and the viscosity of SSBNL is high upon utilization in the system. At the same filler volume, the thermal conductivity value of SSBNL is high. Consequently, SSBN meets the requirements for high filler volume, while SSBNL meets the requirements for a high thermal conductivity value.

Spherical Boron Nitride Powder FAQs

Q1: What are the main properties of spherical boron nitride powder?

A: Key properties include high thermal conductivity, excellent electrical insulation, chemical inertness, high thermal stability, lubrication properties, and improved flowability due to its spherical shape.

Q2: How is spherical boron nitride powder produced?

A: Spherical boron nitride powder is typically produced through methods such as chemical vapour deposition (CVD), spray drying, or plasma treatment. These processes help achieve the desired spherical form and high purity.

Q3: What should be taken into account when handling and storing spherical boron nitride powder?

A: Spherical boron nitride powder should be stored in a dry, cool environment to prevent moisture absorption. Suitable protective equipment should be used to avoid inhalation and skin contact during handling.
