Factory Supply High Pure Graphite Crucibles For Induction Furnace

Properties of Graphite Crucibles:

High Temperature Resistance:

Graphite crucibles can withstand temperatures up to 3000°C (5432°F) in inert atmospheres, making them ideal for melting and holding metals and alloys.

Thermal Shock Resistance:

They exhibit excellent resistance to thermal shock, meaning they can endure rapid temperature changes without cracking or breaking.

Chemical Inertness:

Graphite is chemically inert to most acids, alkalis, and corrosive substances, making it suitable for use in chemical processing.

High Thermal Conductivity:

Graphite crucibles heat up quickly and distribute heat evenly, ensuring efficient melting and processing of materials.

Low Adhesion:

Molten metals and alloys do not easily adhere to the surface of graphite crucibles, making them easy to clean and reuse.

Applications of Graphite Crucibles:

Metallurgy and Foundries:

Used for melting and casting metals such as gold, silver, copper, aluminum, and their alloys.

Commonly used in induction furnaces and other high-temperature melting processes.
