Ultra High Purity Porous Ceramics
Mott’s high purity ceramic technology, utilizing ultra high purity porous ceramics, can be tailored to meet unique application requirements. This ceramic technology provides a broad spectrum of chemical compatibilities and robustness in high temperature and pressure scenarios. High purity porous ceramics, especially porous alumina (or aluminum oxide Al2O3), are recognized for their mechanical strength, wear resistance, and resilience in corrosive settings.
These ceramics have a maximum operating temperature of 2,750 degrees Fahrenheit and can withstand pressures up to 5,000 psi. Their geometric flexibility allows them to be crafted into various forms, from small tubes or bushings to discs, plates, or even electrostatic chucks. The durability and adaptability of porous ceramics enable a plethora of applications across diverse sectors.
Manufacturing these ceramics in a Class 100 clean room environment with >99.5% pure alumina ensures unparalleled cleanliness. The inherent properties of high purity alumina materials, such as high temperature stability, impressive hardness, corrosion resistance, minimal thermal expansion, and a high melting point, make them ideal for components in CVD processes, ion implants, and other semiconductor processes.

These ceramics are especially suitable for applications requiring the highest purity standards.
Q: To what level do Mott’s high purity ceramic products handle extreme temperatures and pressures?
A: Mott’s high purity porous ceramics can operate at temperatures up to 2,750 degrees Fahrenheit and withstand pressures of up to 5,000 psi. This makes them ideal for demanding applications that require resilience to extreme conditions.
Q: In what forms can Mott’s porous ceramics be manufactured?
A: Mott’s porous ceramics exhibit high geometric flexibility. They can be crafted into various shapes such as small tubes, bushings, discs, or showerhead plates, catering to diverse application needs. Mott is currently developing 3D printing of ceramic parts to fabricate complex geometries to include precise porosity where needed.
Q: What are the primary benefits of using porous alumina in high purity ceramic applications?
A: Porous alumina, or aluminum oxide Al2O3, offers outstanding mechanical strength, wear resistance, and resistance to corrosive environments. Its high stability at elevated temperatures, impressive hardness, excellent corrosion resistance, low thermal expansion coefficient, and high melting point make it valuable across many industries, especially in semiconductor processes.
Q: Can Mott’s porous ceramics be used in electrostatic chuck applications?
A: Mott can provide critical components of an electrostatic chuck to extend its useful life and improve its thermal management performance. For example, our advanced porous ceramic plugs are crafted from high purity alumina with meticulously engineered pore sizes, enabling reliable and uniform cooling gas flow. Their inherent high voltage breakdown strength allows them to operate for extended periods without arcing events, thereby enhancing the productivity of the overall semiconductor tool. With this reduced risk of arcing events that typically cause yield-limiting debris combined with a more uniform backside cooling, you can now maximize the performance of your process chamber through enhanced process control and more predictable maintenance schedules.
Q: What makes porous alumina a preferred material for high purity ceramic applications?
A: Porous alumina, also known as aluminum oxide (Al2O3), is a ceramic material renowned for its exceptional mechanical strength, wear resistance, and resilience in corrosive environments. Its properties, such as high temperature stability, hardness, corrosion resistance, low thermal expansion coefficient, and a high melting point, make it invaluable for various industries. Mott’s high purity porous alumina ceramics are manufactured with over 99.5% pure alumina, ensuring optimal performance and purity for critical applications.
