Product Description
High quality magnesite is the majoritary component of magnesia cupels.
As a rule of thumb, magnesia cupels have a superior quality and offer many advantages:
Great mechanical strength, and are not affected by atmospheric conditions (not hygroscopic). .
The prill or bead does not adhere to the fire assay cupel surface,
When using magnesia cupels, the assay have a reduced tendency to freeze.
No cracking or spiting, and the beads do not attach to the fire assay cupel surface.
Magnesia cupels provide security and quickly absorb great amounts of litharge without cracking or pitting.
Our magnesia cupels allow to reduce the Cupellation temperature and time, resulting in minimal losses, higher accuracy and better yields.
Perfect uniformity of Quality of cupels
Quality and performance are continuously improved
Magnesia cupels swiftly absorb 70% of their weight in litharge (PbO) at 980ºC without leaking.
