Quartz Crucible/Ceramic Crucible/Graphite Crucible/Crucible
Select melting ceramic as material, made by advanced quartz technology, mainly apply to platinum, gold and other high temperature alloy melting. Products have the features of high purity and corrosion resistance . Most composition is SiO2(>=98.0%),and others is <=(K2O,Na2O,Fe2O3)0.10%. High in hardness, and pressure resistance is≥70MPa,high thermal shock resistance.
we can design and product the crucibles according to your size and desire
