Boron Nitride Ceramic Material

Boron Nitride Ceramic Material

Boron Nitride Ceramic Material is widely used in machinery, metallurgy, chemical industry, electronics, nuclear energy and aerospace fields. It has excellent performance and great development potential. Boron nitride is a crystal composed of nitrogen atoms and boron atoms. The chemical composition is 43.6% boron and 56.4% nitrogen, and the theoretical density is 2.27g / cm3. Boron nitride coating has the properties of looseness, lubrication, lightweight, easy to absorb moisture. And the color of boron nitride materials is white. Boron nitride products are ivory white.

Boron Nitride Ceramic Material Features

  1. Non-abrasion, low wear, dimensional safety, good lubricity, fire resistance and easy processing.
  2. It has the advantages of good dielectric strength, low dielectric constant, low loss at high frequency, microwave penetration, and good electrical insulation.
  3. High thermal conductivity, high thermal capacity, low thermal expansion, thermal shock resistance, high-temperature lubricity, and stability.
  4. Non-toxic, chemical stability, anti-corrosion, anti-oxidation, low humidity, biological stability and non-stick properties.

Boron nitride coating is an inert inorganic high-temperature lubricating material, which does not bond or infiltrate molten metal. It can completely protect the surface of refractory materials or ceramic utensils, and greatly extend the life.

Boron Nitride Ceramic Material

Boron nitride ceramic material can be used in aluminum, magnesium, zinc and other alloy casting, gravity/low pressure casting, forging, powder metallurgy and other fields. It is widely painted on the surface of the trough and launder, distribution launder, casting table lining, filter box, alumina ceramic ring, cast tip and nozzle material, impurity separation ring, ladle and other materials to protect the mold from corrosion and extend the service life of refractory materials.

At the same time, in the production process, the fine impurities are prevented from penetrating into the molten metal, causing secondary pollution and greatly improving product quality.
It has excellent lubricity and anti-oxidation ability under high temperature environment. With boron nitride for its unique physical and chemical properties, it still protects its unique lubricity, non-sticking property, and resistance to metal corrosion even at extremely high temperatures.

In addition to the protection of various refractory materials, it also has excellent anti-chemical corrosion and anti-adhesion protection effects.
