Ilmasil™ Quartz Glass

Fused quartz is a preferred high-performance material for many future-oriented industries:
Ilmasil™ fused quartz is the unique speciality glass for high temperature applications up to 1300°Celsius. Where Borosilicate reaches its limits, quartz glass takes over with its thermal shock resistance, purity and transmission - for semiconductors, special light sources, industrial & chemical solutions, fiber optics, PV-industry and analytics & laboratory.

Strong durability, high UV transmittance and exceptional purity

Quartz glass is resistant to changing temperatures and aggressive chemicals and is therefore suitable for applications under extreme conditions. Due to its very high UV transmission capacity, quartz glass is an essential material in photonics. Its high degree of purity is essential for various industrial solutions such as analytics & laboratory, PV-application, and fiber optics.

Plasma melting for high cost efficiency and flexibility

Thanks to our advanced process, hollow cylinders are produced in a single step. This results in a high efficiency of energy and raw material and advantages of high cost efficiency and flexibility. fused quartz hollow cylinder are avalible in a wide range up to OD 800 mm.

Product variants

We offer hollow cylinders (OD 105–800 mm), tubes & capillaries (0.5–1000 mm), flat and oval tubes, solid blocks, custom profiles, and high-quality fabricated quartz — tailored to your application needs.
