Product Description

Product Description

Boron Nitride Ceramics

Boron nitride ceramic is an advanced ceramic material with a high melting point, is tough enough to prevent cracks, has high thermal shock resistance, and is easy to process. In addition, molten metal will not wet the surface of the boron nitride, which means it is not prone to clogging during the atomization process.

Under high vacuum, boron nitride can resist up to 1,750 ° C. A gas atmosphere can push it further to 1,900 ° C. This means that boron nitride will remain solid through the melting of most metals. Boron nitride has very low thermal expansion. Coupled with high thermal conductivity, this ensures that the material has very high shock resistance. It can easily withstand rapid changes in temperature inside the atomizer. It will not crack or break under thermal stress.

Boron Nitride Ceramic Tube

Excellent thermal conductivity:
It has extremely high thermal conductivity (about 50-400 W/(m·K)) along the hexagonal crystal plane, which is comparable to some metals and even exceeds stainless steel and alumina ceramics.Good anisotropic thermal conductivity: The thermal conductivity along the c-axis is low, and this property can be used in some heat dissipation designs.

Boron Nitride Ceramic Rod

Excellent electrical insulation:
It has extremely high resistivity (>10^14 Ω·cm) and high breakdown field strength (>30 kV/mm), making it an ideal high-temperature insulation material.
It can maintain good insulation properties even at high temperatures (far above 1000°C).

Boron Nitride Ceramic Ring

Excellent high temperature resistance:
In an inert or reducing atmosphere, the operating temperature can reach more than 2800°C.
In air, due to oxidation (the initial oxidation temperature is about 800-1000°C), the long-term use temperature is usually limited to below 900°C (which can be increased by coating or modification).

Boron Nitride Ceramic Shaft Rod

Good chemical stability:
It has strong resistance to corrosion and wetting for most molten metals (such as aluminum, magnesium, zinc, copper, silver, gold and their alloys, molten steel), glass melts, molten salts (such as fluorides), acids (except hot concentrated alkalis) and slags.
It is very stable in an inert atmosphere.

Boron Nitride Ceramic Shaft Part

Low thermal expansion coefficient:
The thermal expansion coefficient is low (about 1-8 × 10^-6 /K) and anisotropic (lower in the direction parallel to the layer and higher in the direction perpendicular to the layer), which makes it have good thermal shock resistance.
Low density:
The density is about 2.27 g/cm³, which is lighter than most engineering ceramics (such as alumina and silicon carbide).
