1. Ceramic Adhesives:

- Alumina-based ceramic adhesives are designed specifically for bonding and repairing alumina and other high-temperature ceramic materials.

- These adhesives typically have excellent thermal and chemical resistance, as well as high-temperature stability.

- Some examples of alumina-based ceramic adhesives include:

- Cotronics Resbond 931 High Purity Alumina Adhesive

- Aremco Ceramabond 569 High Purity Alumina Adhesive

- Aremco Ceramabond 571 High Purity Alumina Adhesive

2. Epoxy Adhesives:

- Certain epoxy adhesives can also be effective for sealing cracks or leaks in alumina ceramics, especially if the operating temperatures are not too high.

- Look for epoxy adhesives that are specifically formulated for high-temperature, high-strength bonding of ceramic materials.

- Examples of suitable epoxy adhesives include:

- Loctite EA 9483 High-Temperature Epoxy Adhesive

- Devcon Ceramic Epoxy

- J-B Weld High-Heat Epoxy

When selecting the appropriate adhesive or epoxy, consider the following factors:

- Operating temperature range: Ensure the adhesive can withstand the expected temperature range of your application.

- Chemical resistance: Consider the chemical environment the alumina ceramic will be exposed to, and select an adhesive with compatible chemical resistance.

- Thermal expansion compatibility: Choose an adhesive with a thermal expansion coefficient close to that of the alumina ceramic to minimize thermal stresses.

- Surface preparation: Properly clean and prepare the alumina surface according to the adhesive manufacturer's recommendations for optimal adhesion.
