- Size (L*W*H): 40.48*40.48*50.84mm(max)
- Outer Diameter (Max.): 40.48mm
- Outer Diameter (Min.): 33mm
- Inner Diameter: 30mm
- Height: 50.84mm
- Pilot hole diameter: 2mm
Manufactured from high-purity alumina ceramic, the crucible offers excellent resistance to high temperatures, thermal shock, corrosion, and chemical attack, while maintaining reliable dimensional stability under demanding operating conditions.
It is widely used in laboratory experiments, molten material processing, powder sintering, thermal analysis, material flow testing, and other industrial or research applications requiring controlled outlet or venting functionality.
Various sizes, hole diameters, shapes, and alumina purity grades are available to meet different application requirements.
Frequently Asked Questions
Due to the thermal expansion properties of the alumina material, heating or cooling too rapidly can cause thermal shock and lead to cracking. To extend the product life, it is recommended to warm up and cool down as slowly as possible, avoiding direct exposure to temperature extremes.
