The primary difference between quartz tube and glass tube lies in their material composition, thermal properties, and applications. Quartz tubes are made from either natural or synthetic quartz sand, which gives them superior thermal shock resistance and a higher maximum operating temperature compared to glass tubes. Glass tubes, on the other hand, are typically made from less pure materials and are not as resistant to thermal shock or high temperatures.
Material Composition: Quartz tubes are made from quartz sand, which is either natural or synthetic. This material is highly pure, often 99.99% pure, and is known for its excellent thermal and electrical properties. Glass tubes, in contrast, are made from a mixture of various minerals and chemicals, which can include soda-lime, borosilicate, or other formulations. The purity and composition of glass are generally lower than that of quartz, affecting its thermal and mechanical properties.
Thermal Properties: One of the most significant advantages of quartz tubes is their ability to withstand high temperatures and thermal shock. Quartz tubes can operate at temperatures up to 1200°C and can handle rapid temperature changes from 1000°C to room temperature without breaking. This is due to their extremely low coefficient of thermal expansion. Glass tubes, especially those made from soda-lime, cannot withstand such high temperatures or rapid temperature changes and are more prone to thermal shock.
Applications: Quartz tubes are used in high-temperature applications such as semiconductor manufacturing, vacuum brazing, and aerospace testing. Their transparency also makes them useful for applications where visibility is important, such as in some laboratory settings. Glass tubes, while also used in laboratories and industry, are more commonly found in lower-temperature applications due to their lower thermal resistance.
Durability and Maintenance: Quartz tubes, while highly durable under extreme conditions, have limitations in terms of the number of heat-cool cycles they can withstand compared to other materials. For instance, when used at 1200°C, quartz tubes should not exceed 3 hours of continuous use due to their softening point at 1270 degrees. Proper maintenance and usage are crucial to extend the lifespan of quartz tubes.
In summary, quartz tubes offer superior thermal properties and are suitable for high-temperature and thermal shock-prone environments, making them ideal for specialized industrial and research applications. Glass tubes, while versatile and widely used, are generally more suited for applications that do not require extreme thermal resistance.
