►Details:
Crucibles are smaller containers used for the melting of materials, e.g. minerals and glass. Saggars and crucibles can be split into five sub-categories as follows: Round Saggars, Square Saggars, Special Saggars, Round Crucibles and Special Crucibles.
►Feature:
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.
