Carbon Carbon Composite Crucibles
Max Graphite supplies carbon carbon composite crucibles for high-temperature processing environments where conventional graphite falls short. Available in 2.5D, 3D, and 4D fiber architectures, every crucible is produced to customer drawings with controlled deposition processes that deliver dimensional consistency, low ash content, and reliable service above 2000°C — backed by single-source supply capability from material selection through final inspection.

The Crucible at the Center of Your Most Demanding Process
CFC crucibles are specified where the process leaves no margin for error — crystal growth, vacuum sintering, rare earth processing, and high-temperature furnace operations where dimensional stability, purity, and structural integrity under sustained thermal load are non-negotiable. Max Graphite produces carbon carbon composite crucibles from engineering drawings across multiple fiber architectures and density grades, with the process consistency your production schedule demands and the material traceability your procurement team requires. Every crucible is manufactured under controlled CVD/CVI deposition conditions to meet the structural and thermal performance your application specifies.
- Custom geometries, any scale. Produced from customer drawings in round, square, rectangular, and complex profiles — no standard sizes, no compromises on fit.
- Multiple fiber architecture options. 2.5D, 3D, and 4D constructions available — engineered to match your load conditions, thermal gradient profile, and target service life.
- Low contamination, high-purity processing. Ash content controlled to ≤100 ppm, making our CFC crucibles appropriate for semiconductor, solar, and other contamination-critical environments.
- Extended service life vs. graphite. CFC crucibles outlast graphite in high-cycle furnace environments — reducing replacement frequency and improving total cost of ownership per production run.
- Single-source supply capability. Max Graphite manages material selection, fabrication, and quality review under one roof — simplifying qualification and reducing supplier risk.
