XTL sintyron 99.7 bn boron nitride ceramic plate for semiconductor industry

Product Instruction

boron nitride plate is a component made from boron nitride (BN), a synthetic ceramic material known for its exceptional

thermal, electrical, and mechanical properties. Boron nitride exists in several crystalline forms, with the most common being

hexagonal boron nitride (h-BN) and cubic boron nitride (c-BN).

Properties of Boron Nitride Plates:

1.Thermal Conductivity:

High thermal conductivity, especially in the case of hexagonal boron nitride, which is often referred

to as "white graphite" due to its layered structure similar to graphite.Excellent thermal management

properties, making it suitable for high-temperature applications.

2.Electrical Insulation:

Boron nitride is an excellent electrical insulator, even at high temperatures.

It maintains its insulating properties in both hexagonal and cubic forms.

3.Chemical Resistance:

Highly resistant to most chemicals, including acids and molten metals.

Inert to many reactive substances, making it ideal for use in corrosive environments.

4.Mechanical Strength:

High hardness, especially in the cubic form (c-BN), which is one of the hardest known materials,

second only to diamond.

Hexagonal boron nitride is relatively soft and machinable, similar to graphite.

5.Thermal Stability:

Can withstand extreme temperatures, often up to 1000°C or higher, depending

on the form and purity.

Low thermal expansion coefficient, reducing the risk of cracking under thermal stress.

6.Lubricity:

Hexagonal boron nitride has excellent lubricating properties, even at high temperatures,

due to its layered structure.

Applications of Boron Nitride Plates:

1.Thermal Management:

Used as heat spreaders or insulators in electronic devices, such as in semiconductors, LEDs,

and power electronics.

Ideal for high-temperature furnaces and crucibles.

2.Electrical Insulation:

Employed in high-voltage and high-temperature electrical applications.

Used as insulating plates in capacitors and other electronic components.

3.Metal Casting and Molten Metal Handling:

Used as coatings or plates in contact with molten metals due to their non-wetting properties

and chemical resistance.

Commonly used in aluminum and steel industries.

4.Aerospace and Defense:

Utilized in high-temperature environments, such as rocket nozzles and thermal shields.

Provides lightweight, high-strength solutions for extreme conditions.

5.Lubrication:

Hexagonal boron nitride plates are used as solid lubricants in high-temperature environments where traditional lubricants fail.

6.Semiconductor Manufacturing:

Used as crucibles, insulators, and diffusion barriers in semiconductor production.

Provides a clean, non-reactive surface for high-purity processes.

Forms of Boron Nitride Plates:

Hexagonal Boron Nitride (h-BN):

Soft, machinable, and lubricious.

Used in applications requiring thermal conductivity, electrical insulation, and lubrication.

Cubic Boron Nitride (c-BN):

Extremely hard and durable.

Used in cutting tools, abrasives, and wear-resistant coatings.

Hot-Pressed Boron Nitride (HPBN):

Dense and strong, made by hot-pressing hexagonal boron nitride powder.

Used in high-temperature and high-stress applications.

Advantages of Boron Nitride Plates:

• Lightweight compared to metals.

• Excellent thermal and electrical insulation.

• High resistance to thermal shock.

• Non-toxic and environmentally friendly.
