Alumina Crucible is mainly made of alumina. It is fired at high temperature with a special formula. It is a refractory with high fire resistance. It can withstand temperatures of 1800 degrees Celsius and high temperature resistance. It is usually used for smelting precious metals, nickel And other metals, with excellent chemical resistance and high temperature resistance.
Aluminium oxide is a highly stable compound and highly resistant to corrosion from salts, alkalines and acids. It can be used in the manufacture of thermocouple protection tubes, crucibles，boiler tubes and fire retardant material.
One of the main advantages of alumina ceramic crucibles is their extraordinary resistance to various external factors. These crucibles can withstand a high temperature of 1800 degrees, ensuring consistent performance even in challenging environments. Their chemical resistance prevents them from being affected by the most corrosive substances, making them highly suitable for various industrial applications.
The unique density and rigidity of alumina ceramic crucibles distinguish them from traditional substitutes. With its compact structure and excellent strength, high density also enhances their wear resistance, significantly extending their service life.
Alumina ceramic crucibles excel in effectively transferring and distributing heat. Their impressive thermal conductivity makes them an ideal choice for high-temperature industrial processes, ensuring accurate and consistent heat distribution. This characteristic makes these crucibles indispensable in applications such as metal melting, casting, and heat treatment, where temperature control is crucial.
In order to cater to customer preferences, alumina ceramic crucibles provide excellent quality and reliability. These markets require products with excellent performance, durability, and versatility.
