China Graphite Foil Manufacturers, Suppliers, Factory

Semicorex standard quality high-purity flexible graphite foils and sheets are designed to have an ash content of less than 10 ppm. The low ash content is crucial for demanding processes and systems in high-temperature applications, particularly in industries such as semiconductors, solar, and ceramic.

In high-temperature applications, where extreme heat and harsh conditions are present, the presence of ash can cause issues such as contamination, reduced performance, and potential damage to the equipment or components. By ensuring a low ash content, Semicorex flexible graphite foils meet the stringent requirements of these industries and provide reliable performance.

Manufacture Process

Graphite Foil is manufactured from high purity, high crystalline natural graphite flakes, which are processed into continuous foil by special acid and thermal treatments to produce expanded graphite crystals. The expanded graphite crystals are then formed into foil through a calendaring process without any resins and binders.


Semicorex graphite foil’s extraordinary properties make it a suitable material for a wide range of parts and components in heat treatment furnaces, polycrystalline silicon, semiconductor, solar and other ceramic production equipment.

● Vacuum furnaces

● Inert gas furnaces

● Heat treatment (hardening, carbonization, brazing etc.)

● Quartz glass production

● Carbon fiber production

● Cemented carbide production

● Sintering and hot press applications

● Technical ceramic production, e.g. body armor

● CVD/PVD coating

● Crucibles for SiC crystal pulling
