AC10059 Porous Alumina Disc Dia. 152 mm

Porous Alumina Disc Dia. 152 mm Description

Porous Alumina Disc Dia. 152 mm consists of Al2O3 with a minimum purity of 91% and is shaped into a disc with a 152 mm diameter. Its engineered porous microstructure provides an increased surface area which benefits diffusion, catalytic support, and filtration processes. The alumina’s chemical inertness makes it suitable for applications requiring resistance to oxidation and high thermal stability in controlled industrial environments.

Porous Alumina Disc Dia. 152 mm Applications

Industrial Applications
- Used as a filtration element in fluid handling systems to maintain particle control by utilising its tailored porosity, which extends component service life.
- Applied as a support structure in high-temperature processing units to enhance reaction efficiency by providing an extended active surface area.

Chemical Processing
- Serves as a catalyst support in reaction chambers to achieve improved mass transfer through its porous design, which increases contact between reactants.
- Frequently used in diffusion applications where a consistent microstructure aids in uniform process conditions.

Porous Alumina Disc Dia. 152 mm Packing

The disc is individually packaged in anti-static, cushioned containers to prevent mechanical shock and contamination. Protective moisture barrier bags and foam inserts help maintain the integrity of the porous structure during transit. Products should be stored in a dry, temperature-controlled environment. Custom packaging options are available to meet specific handling and storage requirements.

Frequently Asked Questions

Q1: How is the porosity of the alumina disc controlled during manufacturing?
A1: The disc undergoes a regulated sintering process in which temperature and time are precisely managed, ensuring a consistent pore structure by maintaining controlled particle bonding.

Q2: What factors influence the disc’s performance in high-temperature conditions?
A2: The intrinsic thermal stability of Al2O3 combined with the engineered porosity determines performance. Rigorous thermal cycling tests and microstructural analysis are used to evaluate the operational limits.

Q3: Can the pore size distribution be modified for specific applications?
A3: Yes, adjustments in sintering parameters and raw material grading allow for the modification of pore sizes. Detailed process modifications are implemented based on specific technical requirements.

Additional Information

Alumina ceramics are widely studied for their ability to maintain chemical inertness and high-temperature stability. The development of porous alumina involves detailed control of the sintering process, which directly affects the pore distribution and overall mechanical properties. This understanding is critical in applications that demand both durability and functionality under taxing conditions.

Research in materials science continuously improves the techniques for characterising microstructural attributes. Advances in electron microscopy and spectroscopy methods have enhanced the ability to monitor and optimise pore architecture in alumina, facilitating its use in industrial filtration, catalyst support, and diffusion-critical environments.
