Porous Alumina Disc Dia. 203 mm Packing

The disc is protected in moulded foam trays within sealed, anti-static bags to guard against physical damage and contamination. It is stored under dry, temperature-controlled conditions to maintain its microstructure. Additional measures, such as moisture barriers and cushioned inserts, are incorporated as required. Customised packaging solutions, including label customisation and compartmentalised containers, are available upon request.

Frequently Asked Questions

Q1: How does the porous structure influence thermal performance?
A1: The porous architecture decreases effective thermal conductivity by incorporating air gaps, which act as insulative barriers. This design helps manage heat transfer in environments that require thermal regulation without extensive mechanical reinforcement.

Q2: What factors affect the mechanical strength of this disc?
A2: The mechanical properties are impacted by the high alumina purity (≥91%) and controlled sintering parameters that determine grain boundaries. A systematic quality control process involving microscopic inspection ensures consistent structural performance.

Q3: What are the recommended storage practices for this material?
A3: The disc should be stored in a dry, temperature-sensitive environment, ideally in its original sealed packaging. This avoids exposure to moisture and thermal fluctuations that could alter its porous structure and overall performance.

Additional Information

Alumina ceramics, primarily composed of Al2O3, are widely recognised for their chemical inertness and thermal stability. These characteristics make alumina ideal for applications in high-temperature environments where durability and resistance to oxidation are essential. Researchers and engineers often select alumina materials to achieve a balance between mechanical strength and thermal insulation.

Recent advancements in ceramic processing have improved the control over microstructural properties such as pore size distribution. Enhanced control in these parameters benefits applications ranging from electronic substrates to refractory components, ensuring that the fundamental properties of alumina are leveraged to meet increasingly demanding industrial specifications.
