Zirconia backing mix
A graded dry zirconia powder, MIL-48B, for packing around zirconia crucibles in vacuum furnace applications.
Key benefits
Mit einem Techniker sprechenMatched thermal expansion
Shares the zirconia crucible's coefficient of thermal expansion, so mix and crucible move together through every heating cycle.
Longer crucible life
Matched expansion means the packing keeps supporting the crucible body, extending working life pour after pour.
Cleaner vacuum melts
Stable support through the cycle helps keep the melt clean, with minimum casting inclusions.
Graded dry powder
Supplied as a graded dry zirconia powder, packed consistently around the crucible in the vacuum furnace.
