The glow of success.


Energy-efficient, long-lasting, chic: When LED lamps glow in car headlamps, in the office or in your home, our metals are doing their part:


When things get hot: Crucibles for sapphire production.

The light-generating semiconductor layers in an LED are applied to a substrate using an epitaxial process. Thin sapphire wafers are a suitable substrate material. Sapphire is grown at high temperatures in formed crucibles or pressed-sintered crucibles made from tungsten or molybdenum. For this process, we also supply the appropriate hot zones, shield packs, heaters and numerous spare parts for furnaces.

Components for epitaxial processes.

The semiconductor layers in an LED are applied to the sapphire wafer using the MOCVD process (Metal Organic Chemical Vapor Deposition) or MBE process (Molecular Beam Epitaxy). We supply temperature-resistant components made of molybdenum, tungsten and special alloys for the coating reactors.

Powered up: Boats and coils.

Our customers often deposit a reflector layer on the semiconductor. This reflective layer guides the scattered light in the right direction. During the coating process, evaporation boats and evaporation coils made from molybdenum, tantalum, tungsten and their alloys heat up the material for evaporation. Our evaporation boats and evaporation coils are electrically conductive, have low vapor pressures and very high melting points.


A solid foundation: Carrier plates made of molybdenum and MoCu.

LEDs are approximately three times more efficient than conventional lighting. However, LED chips also give off heat. With molybdenum and our in-house developed MoCu discs, PLANSEE is able to call on the perfect materials. Our carrier plates can be joined particularly well to the semiconductor and dissipate heat reliably.


Lovely colors: Phosphor.

GTPAn LED glows in a specific wavelength range depending on the semiconductor materials that have been chosen. In short: An LED glows in a color. One reliable, economical way to convert blue or even UV light into light that is pleasant to the human eye is to coat the LED with phosphor. The phosphor is stimulated by the light of the LED itself to emit a yellowish light - with the result that the light from a blue LED can be combined with yellow light from the phosphor to produce pleasant color temperatures. In the Plansee Group, our US affiliate GTP produces the necessary high-purity phosphor.


Cool heads: Heat spreaders for high-performance LEDs.

When things get hot in high-performance LEDs, PLANSEE's heat spreaders made from tungsten, molybdenum, MoCu, WCu and Cu-MoCu-Cu laminates make sure that the components keep cool.


Precision optics: Forming tools for lenses.


Ceratizit And the Plansee Group also makes sure that the housings do their job: The LED is sealed in a glass lens to ensure that the bundled light radiates in the required direction and the semiconductor is protected. CERATIZIT`s tool specialists manufacture forming tools that are used to produce these precision lenses.
