What is the maximum operating temperature of the 99.3% alumina ceramic arc crucible?
The product description does not specify a maximum operating temperature. However, as a 99.3% alumina ceramic crucible, it is suitable for high-temperature applications typical of alumina ceramics, but users should verify temperature limits with the manufacturer for their specific process.
Does the 50 mL alumina arc crucible fit standard laboratory crucible holders?
The crucible has a top outer diameter of 1.890 in (48 mm), a lower outer diameter of 1.181 in (30 mm), and a height of 2.047 in (52 mm). These dimensions should be confirmed against the receiving holder or furnace workspace before procurement to ensure proper fit and clearance.
What is the wall thickness of the 99.3% alumina ceramic arc crucible?
The wall thickness ranges from 0.118 to 0.138 in (3 to 3.5 mm). This dimensional specification is critical for thermal shock resistance and mechanical integrity during high-temperature cycling in laboratory workflows.
The 99.3% alumina ceramic arc crucible (50 mL) offers a defined geometry and wall thickness for direct replacement in high-temperature workflows, but its 99.3% purity and arc shape impose constraints on thermal shock resistance and holder compatibility.
Positive
- 99.3% alumina ceramic purity: The 99.3% alumina composition provides a chemically inert contact surface suitable for high-temperature melting and ashing applications where contamination from the crucible material must be minimized.
- Defined outer geometry for fit: The specified top OD (48 mm), lower OD (30 mm), height (52 mm), and wall thickness (3-3.5 mm) enable precise dimensional matching to existing holders, furnaces, or process setups without requiring custom adaptation.
Trade-offs
- Thermal shock sensitivity: Alumina ceramic at 99.3% purity has lower thermal shock resistance compared to higher-purity or composite alternatives, requiring controlled heating and cooling rates to prevent cracking during rapid temperature changes.
- Arc shape limits holder compatibility: The arc-shaped geometry may not fit standard cylindrical or flat-bottom crucible holders, necessitating verification of holder clearance and support structure before deployment in existing laboratory setups.
