Alumina Boat，Al2O3
Alumina boats are made of high-quality alumina through multiple fine processing techniques. Its high temperature resistance makes it a commonly used instrument in laboratories and industries. Alumina ceramic trays and alumina ceramic boats can withstand high temperatures of 1600°C, or even higher in some special atmospheres. Ceramic trays and ceramic boats are used for sintering and heat treatment of ceramics, metals and other materials. Their high temperature stability makes them less likely to react with samples.
We have a variety of purities for you to choose from. Alumina boats of different purities have slightly different properties. The higher the purity, the stronger its heat and high temperature resistance. For example, 99 alumina ceramics can withstand higher temperatures than 95 alumina ceramics, and all kinds of properties are more superior.
If you have demand for high-quality alumina ceramic trays、rectangle alumina ceramic boat crucible,please contact us. Our professional team can provide you with customized ceramic boat crucible of different purity and specifications.

*The table above only shows typical properties of common alumina materials. The characteristics of custom alumina ceramic boats will vary depending on the purity and process chosen.
Alumina boat uses
- High temperature sintering and heat treatment of materials：Other materials can be placed to help with high-temperature sintering and heat treatment, such as annealing, quenching, tempering, etc.
- chemical reactor：Its resistance to chemical corrosion allows it to store chemicals and serve as a reactor for some reactions.
- Powder drying and baking: used to place chemical powder to help dry and bake it.
- Elemental analysis: Alumina boats can place samples and heat them in a high-temperature furnace for elemental analysis.
Why choose us?
We have a professional advanced ceramic production plant with 15 years of professional experience and many technical research results in the production of advanced ceramics. We have a variety of advanced ceramic products with crucibles for you to choose from, such as alumina boats, alumina crucibles, rectangle alumina ceramic boat crucible, etc.
We only produce high-quality ceramic boats, using the best raw materials and equipment. In the preparation of raw materials, we grind alumina to submicron particles to ensure the best performance of ceramics during subsequent molding and sintering.
In the molding process, we use a variety of advanced equipment, such as injection molding machines, isostatic pressing machines (CIP), hot pressing machines, etc. These equipment and the operation of our professionals ensure the quality of alumina ceramic products.
Sintering is a very critical step in the ceramic manufacturing process. We use a rapid sintering furnace (RAPID) to ensure quality while greatly shortening the ceramic sintering cycle. We also have microwave sintering furnaces, hot isostatic pressing furnaces (HIP) and other equipment for the sintering of different alumina ceramics. Our professionals strictly and accurately control the sintering time and temperature of ceramics to further improve the performance of alumina ceramics.
We conduct strict product inspections on the alumina boats we produce, and ensure that the quality meets the standards while achieving the smallest reasonable tolerance!
A group of R&D teams with rich professional knowledge are always at your service. We enjoy a good reputation at home and abroad and are appreciated by many partners.
We can provide you with
Multiple purity options: 95% and 99% alumina boats.
Customized service: Products of various specifications and sizes can be customized according to your drawings and requirements.
