Material
The alumina crucible is made from 99.70% high-purity alumina powder through compression molding.
Special Features
- High porosity: It has a high porosity, which helps improve its thermal conductivity and thermal shock resistance.
- Strong thermal conductivity: The crucible exhibits excellent thermal conductivity, allowing for even heat distribution to dental prosthetics and preventing warping and deformation due to uneven heating.
- Reusability: Thanks to its special properties, the crucible can be reused multiple times.
- Structure and Dimensions:
- Outer diameter: 100mm
- Inner diameter: 90mm
- Height: 35 or 32mm
- Upper cover diameter: 100mm
- Upper cover thickness: 5mm
High-Temperature Performance
- Insulation and mechanical strength: The alumina crucible exhibits good high-temperature insulation and mechanical strength.
- High thermal conductivity, low thermal expansion: The crucible has a high thermal conductivity and a low thermal expansion rate.
- Non-reactivity with specific gases: It does not react with air, water vapor, hydrogen, carbon monoxide, and other gases at temperatures above 1700℃.
- Short-term maximum operating temperature: It can withstand temperatures up to 1800℃.
These characteristics make the alumina crucible an essential accessory for the zirconia sintering process in dental prosthetics. It can be stacked in an alternating manner to increase the sintering quantity in the furnace. With excellent heat conduction and high-temperature resistance, it ensures a smooth sintering process for dental prosthetics.
Note
Can choose with cover or not.

Can Crucible be customised for our process?
Yes. Chamber or tube size, temperature profile, atmosphere, gas path, control system and data recording can all be adapted. Send us your process conditions and sample details and our engineers work out a configuration with you.
What warranty comes with Crucible?
Most ZYLAB products carry a 2-year warranty, glass components excluded; the exact term for this model is the one printed in its specification table and repeated on the quotation. Within the warranty period any part that fails through no misuse of your own is replaced free of charge.
How can we pay for Crucible?
Bank (wire) transfer, letter of credit for larger orders, major credit and debit cards, and PayPal. Bank details are printed on the invoice; send us the transfer confirmation and we start processing straight away.
How is Crucible packed for export?
Packing is chosen for the safety of the machine against freight cost, typically a plywood or wooden crate with internal padding and vacuum-sealed accessories. Export documents such as Form A, Form E and Form F can be issued to help you save duty.
