Made from high-tech Al2O3 Alumina Ceramic rings. Alumina ceramic rings is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness.
Alumina ceramic is the material of choice for alumina wear parts. The proven wear and heat resistance of alumina wear parts makes them ideal for the manufacture of wear-resistant components.
Alumina has a high melting point, high hardness, although mechanical strength is reduced at temperatures above 1000 C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced.
Alumina is an electrically insulating material, with a high electrical resistivity, increasing with purity.
Good chemical stability of alumina leads to high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Testing has shown that the low chemical solubility of alumina ceramics components makes them highly resistant to chemical corrosion. This is what makes high purity alumina the material of choice for components in a wide range of industrial applications.
Special offer: Most of our crucibles are produced to OEM order, please mark clearly height, bottom diameter, top diameter, wall thickness and any special requirements i.e. lips etc. To speed up quotations please supply a drawing and if appropriate, the name of the system in which they are to be used.
