What are the dimensional constraints for integrating the 750 mL alumina ceramic arc crucible into an existing furnace or holder?
The crucible has a top outer diameter of 112 mm (4.409 in), a lower outer diameter of 70 mm (2.756 in), a height of 132 mm (5.197 in), and a wall thickness of 5–6 mm (0.197–0.236 in). These dimensions must be verified against the receiving holder or process setup to ensure proper clearance and fit before quotation.
Does the 99.3% alumina ceramic composition impose any handling or thermal cycling limitations for high-temperature arc melting applications?
The crucible is fabricated from 99.3% alumina ceramic, a material known for high-temperature stability and chemical inertness, but the source does not specify maximum operating temperature or thermal shock resistance. Users should confirm compatibility with their specific arc melting temperature profile and ramp rates, as alumina ceramics can be susceptible to thermal shock under rapid cycling.
What is the weight and pack configuration of the 750 mL arc crucible for procurement and handling planning?
Each crucible weighs 960 g, and the price basis in the source table is a 5-piece pack. This weight per piece and pack quantity should be factored into handling, storage, and shipping logistics to avoid overloading manual handling equipment or workspace supports.
The 99.3% alumina arc crucible offers a 750 mL capacity with a defined outer geometry (top OD 112 mm, lower OD 70 mm, height 132 mm) and a 5–6 mm wall thickness, supporting holder clearance verification and replacement matching. The 960 g weight and dimensional tolerance range require confirmation against the receiving setup before deployment.
Positive
- High-purity alumina contact surface: The 99.3% alumina ceramic body provides a defined contact material for processes requiring alumina compatibility, with no secondary phases or coatings specified in the source.
- Dimensionally specified for fit checks: Top outer diameter (112 mm), lower outer diameter (70 mm), height (132 mm), and wall thickness (5–6 mm) are explicitly stated, enabling direct verification against holder or workspace clearances.
Trade-offs
- Heavy per-piece mass: At 960 g per crucible, the unit is relatively heavy, requiring careful manual handling and confirmation that the receiving holder or platform can support the load without stress or tipping.
- Wall thickness tolerance range: The specified 5–6 mm wall thickness introduces a 1 mm variation, which may affect thermal distribution uniformity or necessitate tolerance checks for precise fit applications.
