Product Detail
The Alumina Crucible is a laboratory vessel commonly used for the melting and heat treatment of materials at high temperatures. Its main component is high-purity alumina (Al₂O₃), typically with a purity of over 99.5%. This gives it high-temperature resistance, corrosion resistance, excellent mechanical strength, and superior electrical insulation properties.
The types of alumina crucibles include cylindrical, conical, and ceramic boats.Mascera offers customization of crucibles in different shapes and sizes according to customer requirements. Depending on the specific application needs, the crucible surface can be polished or roughened to enhance durability and suitability for different uses.
