5 FAQs of Customized Porosity and Pore Diameter Alumina Porous Ceramic Disc

What is customized porosity in alumina porous ceramic discs?
Customized porosity means adjusting the number and size of tiny holes in the ceramic disc. This is done during manufacturing. The goal is to match specific needs for filtration, airflow, or fluid control. Different applications require different hole structures. Users can request discs with higher or lower porosity based on their project.

How is pore diameter controlled in these discs?
Pore diameter is controlled by changing the materials and processes used. Manufacturers select raw materials with specific particle sizes. They adjust heating temperatures and pressing methods. This creates pores of exact widths. Precise control ensures the disc performs reliably in tasks like filtering particles or gas diffusion.

What applications suit alumina porous ceramic discs?
These discs work in harsh environments. They handle high temperatures, chemicals, and pressure. Common uses include metal melt filtration, fuel cell components, and water treatment systems. The discs also serve as support layers in catalytic reactions. Their durability makes them ideal for industrial settings.

Can these discs withstand extreme temperatures?
Yes. Alumina ceramic material resists heat up to 1600°C. The structure stays stable even during rapid temperature changes. This makes the discs suitable for furnaces, exhaust systems, and high-heat processing. The material does not warp or crack under thermal stress.

How long do alumina porous ceramic discs last?
The lifespan depends on operating conditions. The discs resist wear, corrosion, and chemical damage. With proper use, they last years without needing replacement. Regular cleaning prevents clogging. Avoiding physical impacts or sudden pressure changes also extends their life.
