Porous Alumina Plate Dia. 305 mm Applications

Industrial Filtration and Separation
- Used as a filter element in fluid processing systems to achieve uniform flow by leveraging its controlled porosity.
- Applied as a support material in catalytic reactors to maintain consistent process conditions through its inert alumina structure.

High-Temperature Processing
- Serves as an insulating plate in furnace liners to manage heat distribution by utilizing alumina’s thermal stability.
- Employed in thermal processing equipment as a barrier against extreme temperatures due to its chemical inertness.

Porous Alumina Plate Dia. 305 mm Packing

The plate is secured in a rigid, anti-static container with foam cushioning to minimise mechanical impact. It is wrapped in a protective barrier to prevent surface contamination and moisture absorption. Storage in a dry, temperature-controlled environment is recommended. Custom packaging solutions, including compartmentalised holders and specific labelling, are available to accommodate distinct handling requirements.

Frequently Asked Questions

Q1: What methods are used to control the porosity of the alumina plate?
A1: Porosity is regulated during the sintering process by adjusting temperature profiles and particle packing density. The process is monitored using microscopic techniques to ensure consistency and meet the targeted performance characteristics.

Q2: What are the key handling precautions for a 305 mm alumina disc?
A2: Due to its size and brittle nature, the disc should be handled with care using appropriate lifting equipment and cushioned supports. Avoid impact and sudden temperature changes to maintain structural integrity.

Q3: How does maintaining a minimum purity of 91% impact performance?
A3: Higher alumina purity ensures reduced impurity phases that can affect mechanical strength and chemical resistance. This control is critical in processes where uniform material behaviour and minimal contamination are required.
