Quartz Tubes and Tubing
Fused Quartz Tube | Closed One End | Open Both Ends
Composition
Fused Quartz tube and tubing are made by fusing or melting, naturally occurring quartz crystals. The crystals used are of a very high purity. This process takes place at 3632°F or 2000°C. This requires using high temperature furnace. Fused quartz tube and tubing is normally a transparent. The optical and thermal properties of fused quartz is far superior to those of other types of glass. This is due to its very high purity.
Applications
Fused quartz is used in ultraviolet transmission, clear lens, and other optics for the ultraviolet spectrum. Quartz has low coefficient of thermal expansion. This makes it a useful material for precision mirror substrates. Thermocouple protection tubes are also made from fused quartz. Quartz protection tubes are excellent for molten precious metal applications.
