What is a quartz tube made of?

A quartz tube is made from fused or melted quartz crystals. The crystals used are of very high purity and the melting process occurs at a high temperature of around 3632°F or 2000°C. This requires the use of a high-temperature furnace. The resulting fused quartz tube is normally transparent and has superior optical and thermal properties compared to other types of glass.

Quartz tubes have a variety of applications. They are used in ultraviolet transmission, clear lenses, and other optics for the ultraviolet spectrum. The low coefficient of thermal expansion of quartz makes it suitable for precision mirror substrates. Quartz tubes are also used as thermocouple protection tubes in molten precious metal applications. They are commonly used in laboratories, semiconductors, sight gauges, optics, pharmaceutical and industrial processes. Quartz's shock resistance allows it to withstand harsh environments, making it useful in fields such as IC fabrication, lasers, and water treatment via UV lamps. Quartz is also found in many watches.

Imported quartz tubes can be transparent or milky white. Transparent quartz tubes can withstand temperatures up to 1100 degrees Celsius. It is important to note that quartz tubes have very high thermal shock resistance, meaning they can withstand rapid temperature changes from 1000 degrees Celsius to room temperature.

The transparent quartz tube is made from different types of raw materials, including natural or synthetic quartz sand. These tubes are highly resistant to thermal shock due to their extremely low coefficient of thermal expansion. They also have excellent electrical strength, providing stability under temperature variations.

Quartz ceramic tubes, offered by companies like KINTEK, are made from 99.99 percent pure quartz with excellent tolerances for high temperatures and pressures. These tubes are used in various industrial applications.

In semiconductor manufacturing, the high purity of quartz is valued as it eliminates the addition of metals that could be harmful to the process. Quartz tubes are used in cleaning baths after etching and machining, as well as in tubes undergoing heat treatments.

Fused quartz has superior ultraviolet transmission compared to other elements, making it ideal for lenses and optical devices. In lighting devices, high-purity quartz products help reduce devitrification and provide optimal sag resistance in high-temperature filament and arc lamps. This extends the life of the lamps when operating at elevated temperatures.
