Cupel used for cupellation furnace 6A
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:
l Great mechanical strength, and are not affected by atmospheric conditions (not hygroscopic). .
l The prill or bead does not adhere to the fire assay cupel surface,
l When using magnesia cupels, the assay have a reduced tendency to freeze.
l No cracking or spiting, and the beads do not attach to the fire assay cupel surface.
l Magnesia cupels provide security and quickly absorb great amounts of litharge without cracking or pitting.
l Our magnesia cupels allow to reduce the Cupellation temperature and time, resulting in minimal losses, higher accuracy and better yields.
l Perfect uniformity of Quality of cupels
l Quality and performance are continuously improved
Magnesia cupels swiftly absorb 70% of their weight in litharge (PbO) at 980ºC without leaking.
