Quartz tubes are widely used in industrial and laboratory applications due to their excellent heat resistance, chemical stability, and transparency. However, in certain high-purity applications, such as semiconductor manufacturing, optical instruments, and fiber optics, impurities in quartz tubes can negatively impact product performance. Therefore, removing or reducing impurities in quartz tubes is crucial. Below are some common purification methods along with their advantages and disadvantages: 1. Chemical Cleaning Method Overview: Use high-purity solvents (e.g., deionized water, ammonia, hydrofluoric acid), combined with ultrasonic cleaning, rinsing, or soaking, to remove impurities on the surface of quartz tubes. 2. High-Temperature Treatment Method Overview: Place the quartz tube in a high-temperature furnace to volatilize […]

Quartz tubes, made from high-purity silicon dioxide, are a specialized form of industrial glass with exceptional physical and chemical properties. Due to their efficient heat-generating capabilities, they are commonly used in devices such as electric heaters, ovens, and other heating equipment. Key Testing Methods for Quartz Tubes 1. Resistance Testing Resistance testing helps determine whether a quartz tube is functioning properly. 2. Power Supply Voltage Testing This test ensures that the quartz tube receives the correct voltage for optimal performance.
