ISO-PRESSED CRUCIBLES
Iso-pressed crucibles come with a number of advantages:
* Wide range of qualities.
*Wide range of sizes.
*Smooth internal surface giving a reduction of inclusions.
* Consistent material properties throughout the crucible.
* Cost-effective.
* General purpose.
* Slag-resistant.
Quality | Description | |
