Alumina Ceramic Arc Crucible 20 mL 99.3% Research ATOMFAIR®

What are the dimensional constraints for integrating the 99.3% alumina ceramic arc crucible into an existing arc melting or thermal evaporation holder?

The crucible has a top outer diameter of 1.417 in (36 mm), a lower outer diameter of 0.906 in (23 mm), a height of 1.614 in (41 mm), and a wall thickness of 0.079 in (2 mm). These dimensions must be verified against the receiving holder or process setup to ensure proper clearance and fit before procurement.

Does the 99.3% alumina purity level impose any handling or thermal shock limitations for arc furnace applications?

The crucible is fabricated from 99.3% alumina ceramic, which provides high-temperature stability suitable for arc melting, but like all alumina ceramics, it is susceptible to thermal shock under rapid temperature changes. Gradual heating and cooling cycles are recommended to prevent cracking, and the 2 mm wall thickness should be considered when evaluating thermal gradient tolerance.

What is the weight and pack configuration for the 20 mL arc crucible, and how does it affect procurement planning?

Each crucible weighs 40 g, and the price basis in the source table is a 100-piece pack. This weight per unit and pack quantity should be factored into shipping cost estimates and inventory planning for multi-run experiments or batch processing.
