Large Graphite Block For Graphite Boats

Isostatic graphite is a premium, fine-grained graphite material produced using cold isostatic pressing (CIP) technology. This manufacturing method applies equal pressure from all directions, resulting in a uniform, dense structure with exceptional isotropy-meaning its physical properties are consistent in all directions. The material exhibits excellent mechanical strength, thermal conductivity, and resistance to thermal shock and chemical corrosion.

Thanks to its high purity (typically <0.05% ash) and consistent performance under extreme temperatures, isostatic graphite is widely used in high-precision applications such as graphite boats, heating elements, and semiconductor tooling. Its stable microstructure makes it ideal for CNC machining into complex shapes while maintaining dimensional stability. SHJ-CARBON supplies large-format isostatic graphite blocks tailored for custom graphite boat production, ensuring material reliability from raw block to finished component.

Graphite boats are widely used in following industries but not limited to that:

A graphite boat is a high-performance container made from high purity graphite, designed to handle extreme heat and chemical exposure. In the photovoltaic industry, graphite boats are essential during PECVD (Plasma Enhanced Chemical Vapor Deposition). During this process, the boat holds silicon wafers while thin films are deposited at high temperatures. A stable, pure graphite carrier ensures even heat distribution and prevents contamination-two things that are critical for high-efficiency solar cell production.
