Manufacturing Process of Crucible Graphite
The manufacturing process of crucible graphite focuses on the careful selection of raw materials. Graphite is extracted from natural sources. Purity levels are crucial in this step. High-purity materials yield better performance. In fact, studies show that purity can affect thermal conductivity by up to 30%.
Next, the raw graphite undergoes a grinding process. This transforms it into a fine powder. The particle size is essential for achieving uniform mixing. Advanced milling techniques help refine this particle size. Subsequent mixing with binders and additives is a critical phase. This combination affects the final product's mechanical properties.
Finally, the resulting mixture is shaped and subjected to high-temperature treatment. This helps to enhance the density of the graphite. A significant aspect of this process is the sintering step. It significantly influences the final porosity. Reports indicate that proper sintering can improve strength by more than 20%. However, this process is not flawless. Controlling the temperature and timing requires fine-tuning. Mistakes can lead to lower-quality products and affect performance in applications.
