Alumina Boats Application
It is often used in high-temperature smelting, chemical reactions, laboratory research, and other fields. Due to its high-temperature resistance and chemical stability, alumina boats can withstand extreme working environments and ensure safe and effective operation. At the same time, alumina boats are also widely used in the preparation of high-purity materials, the production of special alloys, etc., providing important technical support for various industries.
Packing of alumina ceramic tubes
As a ceramic material, the Alumina Boat is quite fragile in a lot of cases. Our Alumina Ceramics are carefully handled to minimize damage during storage and transportation. Suitable outer boxes and inner cushioning materials are used, and vacuum packing is also engaged for some of the parts.
