The 99.3% alumina ceramic body provides thermal and chemical resistance but is susceptible to thermal shock if heated or cooled too rapidly. The defined outer geometry and wall thickness must be verified against the receiving holder or process setup to ensure proper fit and clearance.
- Thermal Shock Sensitivity: Avoid rapid temperature changes to prevent cracking of the alumina ceramic body.
- Dimensional Fit Verification: Confirm top outer diameter, lower outer diameter, height, and wall thickness against the receiving holder or process setup before use.
What are the exact outer dimensions and wall thickness of the 99.3% alumina ceramic arc crucible with 1500 mL capacity?
The crucible has a top outer diameter of 5.512 in (140 mm), a lower outer diameter of 3.543 in (90 mm), a height of 6.693 in (170 mm), and a wall thickness of 0.236 in (6 mm). These dimensions are critical for verifying holder clearance and furnace workspace fit before procurement.
Does this 1500 mL arc crucible require any specific holder or accessory for use in high-temperature furnaces?
The product page states that compatible accessories, replacement parts, and consumables can be matched according to the selected configuration. Users should confirm the top and lower outer diameters against their existing holder or process setup, as the arc shape and 140 mm top OD may require a custom support ring or cradle.
What is the weight per piece of the 99.3% alumina ceramic arc crucible, and how does it affect handling?
Each crucible weighs 1880 g (1.88 kg). This relatively high mass for a 1500 mL ceramic vessel means that handling and transfer should be performed with appropriate support to avoid mechanical stress or accidental dropping, especially when loaded with sample material at elevated temperatures.
The 99.3% alumina ceramic arc crucible (1500 mL) offers a defined geometry and high-purity ceramic body suitable for high-temperature laboratory workflows, though its 1880 g mass and 6 mm wall thickness impose handling and thermal gradient considerations.
Positive
- High-purity alumina ceramic body: 99.3% alumina ceramic provides a chemically inert contact surface suitable for high-temperature melting, sintering, and ashing applications where contamination from the crucible material must be minimized.
- Defined outer geometry for fit checks: Specified top OD (140 mm), lower OD (90 mm), and height (170 mm) enable precise dimensional verification against existing holders, furnaces, or workspace constraints before deployment.
Trade-offs
- Significant mass per piece: At 1880 g per crucible, the unit weight may require reinforced handling procedures or mechanical assistance during loading and unloading, particularly in high-throughput or automated furnace systems.
- Thermal gradient risk from wall thickness: The 6 mm wall thickness, while providing structural integrity, may introduce slower thermal equilibration and increased risk of thermal shock during rapid heating or cooling cycles compared to thinner-walled alternatives.
