Durox Alumina Technical Ceramics

Materion's Durox® family of alumina (Al₂O₃) technical ceramics provides a cost-effective solution for applications requiring high thermal and dimensional stability and low thermal expansion within very tight tolerances. Our high-purity alumina ceramics are made in a range of shapes and purities to match your advanced ceramics needs.

Durox ceramics are ideal for applications used in the defense, energy, semiconductor and telecommunications markets. They are extremely reliable in radio frequency (RF) transistors, power electronics and semiconductor manufacturing equipment as they provide excellent thermal conductivity and superior protection from oxygen and water vapor.

DUROX ALUMINA TECHNICAL CERAMICS PROPERTIES AND PURITY

The hardness of our high purity alumina is surpassed only by diamonds, and alumina is only a fraction of the cost. Durox alumina ceramics have excellent RF properties, so manufacturers can rely on these materials to make parts and components subjected to high-temperature environments.

Durox aluminum oxide ceramics (Al₂O₃) come in two grades to meet the requirements of a range of applications:

• Durox 98 ceramic: 97.6% pure Al₂O₃ and the most affordable alumina ceramic option for ceramic components.
• Durox AL ceramic: 99.8% pure and offers higher tensile strength, dielectric strength and thermal conductivity.

MATERION CERAMICS EXPERTS

We can produce Durox alumina ceramics in several standard and custom shapes. These highly engineered materials can be formed through dry-pressing, iso-pressing and extrusion. For small ceramic parts, dry-pressed Durox alumina can be formed into disks, heat sinks, plates, transistor outline (TO) packages, washers, and small resistor cores. For larger shapes, cold isostatic pressed Durox ceramics can be made into tubes, rods, blocks and ceramic crucibles.
