Home Products Technical Ceramics Durox Alumina Ceramics HIGH STRENGTH ADVANCED DUROX® ALUMINA CERAMICS Materion’s Durox family of alumina (Al2O3) technical ceramics provides a cost-effective solution for applications that require dimensional stability, high thermal stability and low thermal expansion in a form that can be made to very tight tolerances. Durox high-purity alumina ceramics come in a range of purities and shapes to match your advanced ceramics needs and demanding specifications. DUROX TECHNICAL CERAMICS PROPERTIES Durox alumina ceramics have excellent RF properties, resistance to etching, high stiffness to weight ratio and biocompatibility. In addition, these technical ceramics offer a wide range of beneficial properties including: High temperature stability Low thermal expansion High dielectric strength Corrosion resistance Optimum wear resistance These high purity alumina offer hardness only surpassed by diamonds, at a fraction of the cost. Thermally conductive alumina technical ceramics provide manufacturers with a material that they can rely on for parts and components subjected to high temperature environments. TYPES OF DUROX CERAMICS Materion’s Durox products give design engineers more choices to fit project needs. Durox alumina ceramics purities include: Durox 98 ceramic - This alumina oxide ceramic is 97.6% pure Al2O3 and is the most affordable alumina ceramic option for ceramic components. Durox AL ceramic - This alumina oxide ceramic is 99.8% pure, offers higher tensile strength, dielectric strength and thermal conductivity.

APPLICATIONS AND FORMS OF DUROX CERAMIC Materion technical ceramics are used by a variety of industries: photonics/ lasers, defense, energy, telecommunications and semiconductor manufacturing. Durox alumina ceramics have become an essential component for semiconductors because they are a cost-effective way to disperse heat evenly, allowing electrical circuits to run more efficiently. Alumina ceramics are an ideal fit for heat sinks, substrates, laser tubing and resistor cores. We can produce Durox alumina ceramics in several standard and custom shapes. These engineered ceramics can be formed through dry-pressing, isopressing 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 can be made into tubes, rods, blocks and ceramic crucibles.
