Description

Quartz Tube from X-Z LAB is made of SiO2 (fused quartz), a base material with excellent physical and chemical performance. The material is fused quartz.

Quartz Tube heat resistance

The softening point of quartz glass is around 1730 C. It serves for a long time under 1100 C, and briefly up to 1450 C. The tube survives processes that destroy ordinary glass. Good thermal stability means rapid heating without cracking. Furnace sight tubes and lamp envelopes run continuously at 1100 C.

Quartz Tube corrosion resistance

Except for hydrofluoric acid, quartz glass shows no chemical reaction with other acids. The same stability protects semiconductor processes from contamination.

Optical and electrical properties

Quartz glass transmits well from UV to IR: over 90% in the visible and more than 80% in the UV. It is an excellent electrical insulator, even under high temperatures. UV curing lamps depend on that UV transmission. The insulation holds at temperatures where plastics fail.

Typical applications

Laser-grade light sources, radiation-grade light sources, and electric light sources. Semiconductor materials processing. Fiber-optical communication. Analytical instruments use quartz for its inert transparency. For finished optics in quartz, see our Optical Lens.
