Graphite Crucibles
Max Graphite supplies graphite crucibles in standard and custom geometries for metal melting, crystal growth, vacuum processing, and high-purity synthesis applications across the semiconductor, metallurgical, and advanced materials industries. Our crucibles are machined from carefully selected graphite grades — isostatic, fine-grain, and high-purity — to meet the specific thermal, chemical, and dimensional requirements of each application. We supply as a single source across the full range of grades and geometries, from prototype through production volume.
The Crucible at the Center of Your Most Demanding Process
Graphite crucibles are specified in processes where contamination, dimensional instability, or inconsistent thermal performance are not recoverable — Czochralski and Bridgman crystal growth, vacuum induction melting, rare earth refining, PVD evaporation, and high-temperature synthesis. In these environments, the grade selection and machining precision of the crucible are not secondary considerations; they determine process repeatability and downstream product quality. Max Graphite brings together grade expertise, in-house machining capability, and application knowledge to supply crucibles that are engineered for the process, not merely sized to fit.
- Grade selection across the full graphite range: Isostatic, fine-grain, and high-purity graphite grades available, matched to application-specific requirements for structural integrity, chemical inertness, and thermal performance.
- Custom geometry machined to drawing: Crucibles produced to customer-supplied dimensions and tolerances, including complex internal profiles, lipped geometries, and non-standard wall configurations.
- Purity-controlled grades for contamination-sensitive processes: High-purity graphite crucibles available for semiconductor crystal growth, precious metal melting, and other processes where melt contamination carries direct cost or quality consequences.
- Supply continuity from prototype to production: Consistent material sourcing and in-house machining ensure grade and dimensional repeatability across orders, supporting qualification processes and volume supply agreements.
- Application engineering support: Our technical team works directly with process engineers and procurement managers to confirm grade suitability, advise on geometry, and support material qualification documentation.
