       Small Cup-shaped Cylindrical Alumina Crucibles Metal Glass Melting Crucible


Application of Alumina Crucibles:

Industrial alumina ceramic crucible is used for testing laboratory and a variety of industrial analysis.

Alumina ceramic crucible

include: arc alumina crucible, square alumina crucible, rectangle alumina ceramic crucible,

column ceramic crucible.



Main features of Alumina Crucibles


1) High hardness.
2) High heat resistance: alumina ceramic has excellentthermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.
3) Good wear resistance: alumina ceramic is the material of choice for alumina wear parts.
4) High electrical resistivity: alumina is an electrically insulating material.
5) High corrosion resistance: it is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
