2. Application of graphite crucibles in carbon-carbon products industry

High temperature smelting:

Graphite crucibles can withstand extremely high temperatures and are suitable for high temperature smelting in the preparation process of carbon-carbon composite materials. It can ensure the stability of the smelting process while reducing material loss and pollution.

Chemical stability:

Graphite crucibles do not participate in any chemical reaction during the smelting process and have strong corrosion resistance to acidic and alkaline solutions. Therefore, they can maintain the purity of the smelting environment, which is conducive to the preparation of carbon-carbon composite materials.

Good thermal conductivity:

Graphite crucibles have excellent thermal conductivity and can quickly transfer heat to ensure the uniformity and efficiency of the smelting process. This helps to improve the preparation efficiency and quality of carbon-carbon composites.

Smooth inner wall:

The inner wall of the graphite crucible is smooth, and the molten metal liquid is not easy to leak and adhere to the inner wall of the crucible, so that the smelted carbon-carbon composite material has good fluidity and castability, which is suitable for casting and molding of various molds.
