Cell Lab High-Purity Alumina (Al₂O₃) Disks [5 pcs / pack]

High-temperature ceramic disks for furnace, insulation and dielectric applications

General Description

Cell Lab high-purity alumina (Al₂O₃) disks are designed for use in high-temperature environments, providing exceptional resistance to heat, corrosion and electrical breakdown. With > 99 % purity, these disks offer high hardness, low thermal expansion, and excellent dielectric properties, making them ideal for tube furnaces, semiconductor processing, and ceramic R&D.

Each pack includes five disks precisely manufactured for dimensional stability and surface uniformity. Custom sizes and surface finishing (polished / unpolished) are available upon request.

Note – Alumina disks are consumable products and are not covered by warranty. Please inspect within one week of delivery; Cell Lab will only be responsible for manufacturing defects reported during this period.

Key Features

  • > 99 % Al₂O₃ purity for superior chemical and thermal stability.

  • Excellent electrical insulation ideal for high-voltage and furnace use.

  • High hardness and low expansion ensure mechanical integrity under thermal stress.

  • Operational up to 1600 °C in oxidising or inert atmospheres.

  • Customisable in diameter, thickness and surface finish (polished / unpolished).
