China Isotropic Graphite Manufacturer, Supplier, Factory

Isostatic graphite, a type of ultra-fine structured graphite, is used in applications where other fine-grained graphites like GSK/TSK fall short. Unlike extrusion, vibration, or mold-formed graphite, this technology produces the most isotropic form of synthetic graphite. Additionally, isostatic graphite typically boasts the finest grain size among all synthetic graphites.

VETEK offers a range of specialty graphite grades suitable for various industries. Praised for their excellent performance and reliability, our products are essential in many everyday applications. In the environmental and energy sectors, our graphite is primarily used in solar cell manufacturing, nuclear energy, and aerospace applications. In electronics, we supply materials for numerous manufacturing processes such as polycrystalline and monocrystalline silicon, white LEDs, and high-frequency devices. Key applications of our products include industrial furnaces, continuous casting molds (for copper alloys and optical fibers), and EDM graphite electrodes for mold making.

Typical Properties of Isostatic Graphite:

1. Isotropic Graphite:Traditional graphite is anisotropic, limiting its use in many applications. In contrast, isotropic graphite exhibits uniform properties across all cross-sectional directions, making it a versatile and easy-to-use material.

2. High Reliability:Due to its micro-grain structure, isotropic graphite has higher strength than traditional graphite. This results in a highly reliable material with minimal characteristic variation.

3. Superior Heat Resistance:Stable even at extremely high temperatures above 2000°C in inert atmospheres. Its low thermal expansion coefficient and high thermal conductivity provide excellent thermal shock resistance and heat distribution properties, with minimal thermal deformation.

4. Excellent Electrical Conductivity: Its superior heat resistance makes graphite the preferred material for various high-temperature applications, such as heaters and graphite thermal fields.

5. Outstanding Chemical Resistance: Graphite remains stable and corrosion-resistant, except against some strong oxidizers. It maintains stability even in highly corrosive environments.

6. Lightweight and Easy to Machine:Compared to metals, graphite has a lower bulk density, allowing for the design of lighter products. Additionally, it has excellent machinability, facilitating precise shaping and processing.
