Alumina Cylinder ， Al2O3
*The above specifications are for your reference only. Alumina cylinders are customized products with different specifications.
Alumina cylinder is a cylindrical alumina crucible produced by us. We provide cylindrical crucibles of various sizes and purities for you to choose from (Diameter 1-550mm customized size, Purity 95-99.9), which can meet your special needs in laboratory or industry.
Our product prices are more competitive than similar cylindrical crucible products. If you order a large number of ceramic crucibles from us (more than 10 pieces) at a time, we will provide you with a 10% discount. The specific price is subject to inquiry.
GORGEOUS strictly controls the quality during the production process. The alumina cylinder we produce has various superior properties, the most prominent of which are strong high temperature resistance (endurance of 1750℃ extreme high temperature) and corrosion resistance (resistance to various acid, alkali and salt corrosion), allowing you to use it safely within the maximum temperature.
In addition to alumina cylinders, we also offer a wide range of ceramic crucible products in various shapes, such as alumina boats, alumina trays, alumina crucibles (bowls) and custom crucibles in special shapes.
The following are the common sizes of alumina cylinder for your reference. Don’t worry if the size you need is not available. We provide special customized services for you. If you need a cost-effective ceramic crucible, please contact us immediately.

Superior performance of alumina cylinder
Excellent high temperature resistance: Our alumina cylinder has excellent heat resistance and thermal conductivity. Ceramic crucibles can withstand high temperatures of 1600°C under normal circumstances, and can be temporarily at 1750°C in some special application scenarios. Our alumina cylinders are precisely manufactured. According to customer feedback, our alumina cylinders can have a 10% longer service life than other similar products, and cracking is very rare during high temperature treatment, which is very beneficial for your high-temperature and efficient treatment of chemicals and molten metal materials.
Strong corrosion resistance: Alumina ceramics have excellent corrosion resistance, which makes alumina cylinders resistant to corrosion from a variety of chemical substances (such as acid, alkali, salt, etc.) and have a good service life. Alumina is a non-toxic inert material. Our products are of high purity (>99%, except for specific purity requirements), with only a small amount of harmless impurities, which can minimize safety hazards during your use. If you are engaged in experimental research and industrial production that requires storage and management of corrosive chemicals, our products are your best choice.
At the same time, based on our years of production experience and customer feedback, we give you the following suggestions on the use of alumina cylinder:
Please be careful to avoid long-term (such as more than 1 hour) contact or high-temperature treatment of the following solutions: hydrofluoric acid solution (HF), high-temperature phosphoric acid solution (H3PO4), high-temperature sodium hydroxide solution (NaOH), boiling point potassium hydroxide solution (KOH). Using these high-temperature solutions may cause the alumina cylinder to be corroded.
Caution: For larger cylindrical crucibles, if the maximum temperature change rate exceeds 160°C/Hr, the crucible will crack.
