Large Graphite Crucible Providing High Purity Essential for Anode Material Graphitization in Manufacturing Operations

Our large graphitization graphite crucible is a high-performance high-temperature container fabricated from high-purity artificial graphite via compression molding, ultra-high temperature graphitization treatment and precision machining. It delivers exceptional temperature resistance (up to 3000℃ in inert atmosphere), excellent thermal conductivity, low thermal expansion coefficient, outstanding thermal shock stability and chemical inertness, maintaining structural integrity and extended service life under cyclic high-temperature graphitization conditions.

Specially engineered for the graphitization process of lithium battery anode materials, this large crucible serves as the core material carrier in Acheson furnaces and other graphitization equipment, holding calcined petroleum coke and needle coke feedstock for high-purity graphitization purification. It also applies to non-ferrous metal melting, powder metallurgy sintering, rare earth purification and photovoltaic material processing. We support full customization of dimensions, wall thickness, geometry and anti-oxidation surface treatment to match diverse furnace types and production processes. As a professional graphite product manufacturer with large-scale production capacity, we provide consistent quality, factory-direct pricing and reliable bulk supply for global new energy and industrial clients.

• Lithium Battery Anode Material Graphitization (Core Application)

  Acts as the key material container in Acheson furnaces and internal-series graphitization furnaces, holding calcined petroleum coke, needle coke and other anode raw materials to complete graphitization purification at 2800–3000℃. It is an essential kiln furniture for mass production of artificial graphite anodes, ensuring stable crystal structure and high purity of final anode materials.

• Non-ferrous Metal Melting & Refining

  Used for large-scale melting, heat preservation and refining of gold, silver, copper, aluminum, zinc and their alloys. Its strong chemical inertness prevents reaction with molten metal, effectively maintaining metal purity, and adapts to intermediate frequency furnaces, resistance furnaces and other melting equipment.

• Powder Metallurgy & Carbon Product Sintering

  Carries metal powder, carbon powder and other raw materials for high-temperature sintering and graphitization. Uniform thermal conductivity ensures consistent sintering quality of green bodies, widely applied in mass production of cemented carbide, structural ceramics and special carbon materials.

• Photovoltaic & Semiconductor Material Preparation

  Applied in high-temperature melting and purification of polysilicon, monocrystalline silicon ingots and high-purity semiconductor materials. High-purity graphite matrix avoids impurity contamination, and large-size design meets the capacity demand of large-scale production lines.
