Westtop zirconia toughened alumina ( ZTA ) rectangular crucible

        Zirconia toughened alumina ( ZTA ) rectangular crucible is a kind of container made of special ceramic materials. It combines the high hardness, high melting point, chemical stability of alumina and the toughness of zirconia. As an excellent refractory material, alumina has good thermal shock resistance and corrosion resistance, but it is brittle. The addition of zirconia can effectively toughen alumina, so that the rectangular crucible is not easy to break when subjected to large mechanical stress. It has excellent performance at high temperature, and can withstand harsh conditions such as sharp temperature changes and chemical erosion in high temperature furnaces to ensure stable use in various high temperature processes.

Specifications and technical performance

specification

        The rectangular crucible has a variety of specifications, with a length of 100mm-500mm, a width of 50mm-200mm, and a height of 30mm-150mm. The above specifications can meet the needs of most customers in different high temperature treatment scenarios such as small laboratory experiments or large-scale industrial production.

technical characteristics

• High temperature stability : It can work stably at 1600-1800 ° C without softening and deformation problems. It can be used in metal melting, glass firing and other processes with extremely high temperature requirements.
• Chemical stability : strong corrosion resistance to a variety of acidic and alkaline substances, such as contact with sulfuric acid, hydrochloric acid and other strong acids, sodium hydroxide, potassium hydroxide and other strong bases do not react, to ensure the purity of the treated material, to avoid crucible material pollution.
• Mechanical properties : Due to the toughening of zirconia, the fracture toughness is significantly improved compared with the traditional alumina crucible, which can withstand certain impact and friction. It is not easy to damage during handling, loading and unloading, and has a long service life.
