Product Description

Isostatic graphite material has excellent performance in thermal conductivity, thermal stability, self-lubrication, anti-wetting, chemical inertia, etc. It is an irreplaceable material for manufacturing crystallizers.


 

Product Description

Isostatic graphite material has a series of excellent properties. For example, isostatic graphite has good heat resistance.

Under the inert atmosphere, the mechanical strength not only does not decrease with the increase of temperature, but increases instead, and reaches the highest value around 2500ºC.

Compared with ordinary graphite, its structure is fine and dense with good uniformity. Extremely low coefficient of thermal expansion, excellent resistance to thermal shock.

Isotropic; strong chemical resistance, good thermal and electrical conductivity; excellent processing performance.

Manufacturing process.

Product Processing Flow

Isostatic graphite is made by using cold isostatic molding technology, filling the raw material powder into a rubber mold and compacting it using high-frequency electromagnetic vibration. Once sealed, the air between the powder particles is evacuated by vacuum. The mold is then placed in a high-pressure vessel filled with a liquid medium such as water or oil and pressurized to 100-200mpa to obtain a cylindrical or rectangular product. This process follows Pascal's principle, which means that pressure is applied to the rubber mold through a liquid medium such as water, ensuring equal pressure in all directions. As a result, the pressed powder particles are compressed into an irregular arrangement in the mold rather than oriented in the filling direction.

Thus, while graphite is crystallographically anisotropic, under isostatic pressure graphite is generally isotropic. Formed products are not only cylindrical and rectangular, but also crucible-shaped.
