5 FAQs of Custom Clay Graphite crucible Graphite Vacuum crucible With Lid High Purity Graphite crucible

What is the maximum temperature a Custom Clay Graphite Crucible or High Purity Graphite Crucible can withstand?
Custom Clay Graphite Crucibles typically handle temperatures up to 1600°C in oxidizing environments and 2000°C in inert conditions. High Purity Graphite Crucibles, made from 99.9% pure graphite, withstand extreme heat up to 3000°C under vacuum or inert gas, making them ideal for melting precious metals, semiconductors, or advanced alloys. The Graphite Vacuum Crucible with Lid is designed for vacuum furnaces, offering similar high-temperature stability while minimizing oxidation.

How do I maintain these crucibles to extend their lifespan?
Avoid rapid temperature changes to prevent thermal shock. Preheat gradually and cool naturally after use. Clean residues with non-abrasive tools or compressed air—never use water or harsh chemicals. For vacuum crucibles, ensure the lid seals tightly to maintain vacuum integrity. Store in a dry environment to prevent moisture absorption, which can weaken graphite. High Purity Crucibles require extra care to avoid contamination from foreign materials.

Can these crucibles be customized for specific applications?
Yes. Custom Clay Graphite Crucibles are tailored in size, shape, and wall thickness to suit furnace dimensions or melting volumes. Vacuum Crucibles often include threaded lids, grooves, or flanges for secure sealing. High Purity variants can be machined with ultra-smooth surfaces for minimal reactivity. Customizations like handles, spouts, or reinforced edges are also available for specialized industrial or laboratory processes.

What makes a Graphite Vacuum Crucible different from standard crucibles?
Vacuum Crucibles feature precision-engineered lids to create airtight seals, preventing oxidation and contamination in vacuum environments. They’re made from high-density, low-porosity graphite to reduce outgassing, critical for processes like crystal growth or vacuum melting. Standard crucibles lack these sealing features and are better suited for open-air or inert gas applications.

Why is high-purity graphite important for certain applications?
High Purity Graphite (99.9%+ carbon) minimizes impurities that could react with sensitive materials like silicon, gallium, or rare earth metals. This is crucial in semiconductor production, aerospace alloys, or research labs where trace elements affect outcomes. Lower-purity clay graphite blends are cost-effective for general foundry use but lack the cleanliness required for advanced tech applications.
