Boron nitride ceramics (BN) has become the star of modern engineering materials with its excellent high-temperature stability and thermal conductivity. It can work stably at extremely high temperatures, especially in a vacuum environment, and can withstand high temperatures above 2000°C. It is widely used in high-temperature furnace components, electronic heat dissipation materials and semiconductor equipment. Boron nitride ceramics not only have excellent thermal conductivity, but also have excellent electrical insulation and chemical corrosion resistance, which is an indispensable key material in the field of electronics, electricity and metallurgy.

What is boron nitride ceramics? -Advanced Ceramic Materials-Zihao Ceramics

Is boron nitride a ceramic?

“Is boron nitride ceramic?” Definitely a ceramic. Boron nitride (BN) is a synthetic ceramic material, which can be divided into hexagonal boron nitride (h-BN), cubic boron nitride (c-BN) and so on according to different crystal structures. In particular, hexagonal boron nitride, also known as “white graphite”, has excellent high-temperature stability and lubricity, is an important material for the preparation of high-performance ceramic products.

Core properties of boron nitride ceramics

Boron nitride ceramics can withstand temperatures up to 2000°C or more, and still maintain a stable structure in an inert atmosphere.

Boron nitride ceramic thermal conductivity is much higher than general ceramics, comparable to metal aluminum, is the ideal material for heat dissipation.

Combining high thermal conductivity and insulation properties, they are commonly used in semiconductor packaging and high-voltage electrical equipment.

Excellent resistance to molten metals, glass, salts and most acids and bases.

Typical applications of boron nitride ceramic products

  • Semiconductor industry: Used for wafer transfer components, thermally conductive insulating substrates.
  • Metallurgical industry: crucibles for molten metal, casting molds.
  • New energy field: battery heat sink, power device packaging materials.
  • Vacuum equipment: electrical insulation and high-temperature insulation parts.
  • Machinery manufacturing: precision wear-resistant parts.

With its unique properties, boron nitride ceramic products have been widely used in aerospace, electronics, metallurgy, new energy and other frontier industries.

Why choose to good ceramics?

In addition to boron nitride ceramics, we are also deeply engaged in the field of silicon nitride ceramics processing manufacturers and silicon nitride ceramics manufacturers, with a wealth of experience in material research and development and advanced production technology, able to provide customers:

  • High-precision customized processing services

  • Multiple ceramic material solutions (boron nitride, silicon nitride, zirconia, alumina, etc.)

  • Stable supply and strict quality inspection

Hot Topic: Boron Nitride VS Silicon Nitride

  • Boron Nitride Ceramics: Excellent in thermal conductivity and temperature resistance, suitable for electronics, heat dissipation and insulation applications.
  • Silicon Nitride Ceramics: Known for their high strength and impact resistance, they are commonly used in mechanical parts and bearings.

Both have their own advantages, customers can choose according to demand, to good ceramics can provide one-stop solution.

common problems

It can be used in vacuum and inert gas environment above 2000℃, commonly used in metallurgical crucible and vacuum furnace parts.

It won't. Boron nitride ceramics combine high thermal conductivity with high insulation, making them ideal for electronic components.

A significant advantage of boron nitride ceramics over most ceramics is that they can be machined with standard tungsten carbide tools such as turning, milling, and drilling, which greatly reduces the difficulty and cost of manufacturing their products.

As a professional manufacturer of silicon nitride ceramics, we, Zhihao Ceramics Co., Ltd, can stably supply boron nitride ceramic products of various specifications and provide customized processing services.

Both have their advantages.

  • Boron nitride ceramics have good thermal conductivity and insulation, and can be machined;
  • Silicon nitride ceramics are stronger and tougher. The choice depends on the specific application scenario.

Of course, we can customize boron nitride ceramic products and other high-performance ceramic parts according to customer drawings and requirements.
