Graphite Barrel

Advantages of graphite barrel

Graphite barrel is mostly of a single-piece molded cylindrical structure, which can also be assembled by piecing together sections.

Extremely high thermal stability

It is able to withstand high temperatures for a long time under vacuum or inert atmosphere conditions, not crack under cold and hot cycles.

Excellent thermal radiation performance

It can maintain a balanced temperature field within the furnace and reducing local temperature differences.

Extremely low thermal expansion coefficient

This results in small deformation at high temperatures and stable assembly accuracy.

Dense overall structure

It is wear-resistant, easy to be drilled, grooved, and coated for secondary processing and has a long service life.

Conduction uniforme de la chaleur

It enables rapid and balanced temperature distribution within the furnace.

Excellente conductivité électrique

It can be adapted to electrical conditions such as electric heating and static load bearing, compatible with various high-temperature conductive heating components.

Uses of graphite barrel

Semiconductor photovoltaics field

Wafer support and temperature field balance

Because it has uniform heat conduction and stable temperature control, you can serve it as a wafer support base. It can eliminate local temperature differences in the furnace and ensure uniform thickness and material uniformity of the epitaxial wafer during growth.

Photovoltaic thermal field accessories

With the excellent sealing performance, you can use it as special inner lining for the purification and annealing processes of photovoltaic silicon materials. It can prevent the high-temperature heat in the furnace from spreading outward, which reduces the heating energy consumption of the equipment. And it does not release impurities that may contaminate the silicon materials, which is suitable for continuous production furnace bodies.

The field of heat treatment and metallurgy

High-temperature furnace insulation liner

You can use it as the internal insulation lining in the vacuum sintering furnace and steel heat treatment furnace. It reduces heat loss and lowering the heating energy consumption of the equipment, and will not produce impurity volatilization under vacuum or inert atmosphere.

Precious metal melting equipment

When melting rare metals and special alloys, you can use it as creusets for the process. It can avoids contamination of the molten materials by impurities, suitable for medium-frequency melting furnaces and vacuum casting equipment.

New Energy Industry

Lithium battery sintering equipment

You use it as the interior of the sintering furnace for lithium battery positive and negative electrode powder materials. It ensures that the cylinder body does not deform or crack during long-term use, improving the frittage quality of lithium battery raw materials.

High-temperature components of fuel cells

Using it in the reaction chamber of the high-temperature fuel cell can stabilizes the internal reaction temperature. And it also extends the continuous operation time of the fuel cell under high-temperature conditions, reducing the equipment replacement cost.

Mechanical high-temperature tooling

High-temperature sintering tool cylinder

You can also use it as the supporting fixtures in the graphite cylinders specially designed for the powder metallurgy and industrial ceramic sintering process. It can ensure that all workpieces are heated synchronously and avoid warping and cracking defects.
