Discover the Benefits of Partnering with Itowu as Your High Thermal Conductivity Ceramic Supplier

Ceramics have long been utilized in various industries due to their excellent properties. One of the most sought-after ceramic materials is high thermal conductivity ceramics. These materials are known for their superior heat dissipation and insulation capabilities. They find applications in various industrial fields, ranging from electronics and metallurgy to aerospace and biomedicine. In this blog, we will introduce you to Itowu's high thermal conductivity ceramics, specifically our BN-A powder supplies for boron nitride ceramics production.

application of boron nitride

Boron nitride is an essential material used across industries due to its exceptional properties. It acts as a release agent in metal forming and lubricant for metal wire drawing. It is also ideal for high-temperature solid lubricants, extrusion anti-wear additives, ceramic composite additives, refractory materials, and anti-oxidant additives. Moreover, it is suitable for heat sealing desiccant of transistor and additive of polymer such as plastic resin. Boron nitride can be pressed into various shapes of components used in high-temperature and high-pressure environments, insulation, and heat dissipation components.

Itowu's BN-A powder

Itowu's BN-A powder supplies for boron nitride ceramics production have several advantages. The hexagonal boron nitride crystal structure has a similar graphite layered structure. It presents itself as a white powder of loose, lubricated, moisture absorption, and light quantity. The theoretical density is 2.27g/cm³, the proportion is 2.43, and the Mohr hardness is 2. It has excellent heat resistance, thermal stability, thermal conductivity, high-temperature dielectric strength, and is an ideal heat-dissipating material and high-temperature insulating material.

Boron nitride ceramic products are mainly used for:

  1. Electrode insulation sleeves for vacuum sintering furnaces and atmosphere furnaces
  2. Thermocouple protection sleeves
  3. Insulation components for vacuum coating equipment
  4. Insulation components for multicrystalline silicon ingot factories
  5. Metal, glass, and other molding molds
  6. Used for sintering and melting alloys, ceramic substrates, rare earths, and other materials.

The operating temperature for boron nitride ceramics can range from 900℃ in the case of oxidation resistance to 2100 ℃ in the case of nitrogen, argon, and other inert gases. It has extremely strong thermal shock resistance, and it can be cooled rapidly for 15 minutes at 1000 degrees to room temperature for 100 times without cracking. Moreover, it has good corrosion resistance, good chemical stability, and a small thermal expansion coefficient.


In conclusion, Itowu's BN-A powder supplies for boron nitride ceramics production are highly sought-after due to their exceptional properties. Boron nitride is widely used across industries, and its excellent properties contribute to its popularity. Apart from BN-A powder, Itowu has many other high quality nitride products too, such as Itowu nitride ceramic, all of which are of high quality, fast delivery time, and customized services. Our products have been sold in various countries, and our customer satisfaction speaks volumes about our expertise in the field.
